LPT : If you are having a party, make sure to hide you valuables and money. I learned the hard way that one of my relative has "sticky fingers".

This happened a couple of years ago but still pisses me off. During a party, one of my relative took half of the money I used to put in a jar. Probably thinking I wouldn't realize it but I did. (I had just counted the amount I had a couple of days before)
I don't know who did it so everyone is still a suspect. It sucks.
