My friends,all my belongings in the hostel,shal I allow it?

I once read about someone who had a similar problem, and he was told that there 3 things which he could do about the situation. He could accept that people were using his things, he could get a lock or something like that or he could tell his friends that it was okay if they wanted to use his things as long as they helped him pay for them, in other words if they wanted to share the things they also had to share the expenses. Personally I think that the second and the third options are the best, and I would suggest that you try one of those things.

tell your friends in a calm friendly manner. like make it seem you're kidding. They'll laugh at it but it'll hit a nerve and they'll realize their mistake. If they don't then they're to thick to be human. If this happens, change your locks. :)

Get something where you can lock your belongings up so your friends won't use them without your permission?!
