From personal experience I do not let people barrow anything anymore. I found out the hard way that most of the time I never get back what I let them barrow. It is really a shame because they are people and friends you are suppose to trust. When you barrow you suppose to give back what it is you barrowed and in most cases it never comes back.I do not even ask others to borrow anything from them. So I do not let anyone barrow anything I own.
