Here's how i feel abouut it mate.
You are 24. Therefore, you are a man.
If gear in your parents house is an issue, then you should respect their wishes and get it out of their house.
Be a man. Do not lie. Tell them it is your gear, and you would like it back. If they say no, then be a man, and let it go.
What I don't like is the slimy Bullshit kids come up with when they get caught doing things. If you did it, then admit it.
No one said being a man was easy.
