Tricks Who Steal your Property

Why do tricks that you invite over and show them trust and are nice to them, pocket items of yours that don't belong to them when your looking the other way? For some guys, its how they fund their expensive habit with illegal drugs, i.e. Crystal-meth. Others do it cause what they are pocketing might be a better model or have more features then theirs. Recently I have been blammed for doing just that, taking something that wasn't mine. It was a beard trimmer. If i had taken it, my beard would have been trimmed and my hair would have been trimmed down a little, but no, its still their and bugging me to death. Ponder on that...
