In this riddle, I go around and into the house but never actually touch the house – what am I?

Introduction / Context:
This riddle asks you to identify something that "goes around and in the house" but "never touches the house". The description suggests something that is present both outside and inside, yet is not a solid object in contact with walls or furniture. The best answer, which fits the riddle in a natural way, is sunlight. Sunlight surrounds a house, enters through doors and windows, and fills rooms, but as an intangible form of energy it does not physically touch the house like a solid object would.

Given Data / Assumptions:

• The subject of the riddle goes around the house.
• It also goes into the house.
• Despite being present, it never touches the house as a solid object.
• The answer should be something that people commonly experience in daily life.

Concept / Approach:
The key to solving this riddle is to think about non material things that can fill space, move freely, and still be described as "going around" or "going in". Both air and sunlight might come to mind. However, the phrase "never touches the house" points us to something that is experienced visually rather than physically. We see sunlight but cannot hold it. Sunlight can shine all around a house and stream into rooms through windows or open doors, yet it has no solid surface. Therefore it is natural to say that it does not truly touch the house in the same sense as concrete objects do.

Step-by-Step Solution:
Step 1: List things that can be outside and inside a house, such as air, wind, sunlight, roads and fences. Step 2: Remove options that are obviously solid and must touch the house if they are near it, such as a fence or a road. Step 3: Consider invisible but physical substances like air or wind; they physically press on walls and objects, so they do "touch" the house in a scientific sense. Step 4: Evaluate sunlight, which illuminates the house and passes through windows without being a solid object that can be physically grasped. Step 5: Conclude that sunlight best matches the description of going around and into the house without touching it as a solid object.

Verification / Alternative check:
To verify, imagine a sunny day. The sunlight falls on all sides of a house and enters rooms through glass windows, doors and small openings. You can see the light, and it enables you to see the interior, but you cannot feel a solid surface of "light" itself. In contrast, a road cannot go inside a house, a fence stays only around it, and electric wires must be fixed and in contact with surfaces. This mental picture confirms that sunlight is the only option that satisfies every part of the riddle.

Why Other Options Are Wrong:
The wind: Wind is air in motion and physically presses on walls and objects, so it does touch the house, even if invisibly.
A road: A road runs outside the house and cannot go inside the building in the normal meaning of the word.
An electric wire: Wires must be attached to walls or structures, so they definitely touch the house.
A fence: A fence can go around a house but not into it, and it obviously touches the ground and sometimes the building itself.

Common Pitfalls:
Some learners may quickly choose "the wind" because it is unseen and goes around houses. However, the riddle emphasises the idea of not touching, which is better matched by light, a form of energy without solid substance. Another common error is to treat the description too literally and try to imagine a physical path or structure instead of something intangible. Remembering that many riddles rely on metaphor and non material phenomena is helpful for avoiding such mistakes.

Final Answer:
The thing that goes around and into the house but never truly touches it as a solid object is sunlight.
