Mamunur, it is indeed sad that you had to learn this truth the hard way. It hurts to find out what people are really liuke. but think of it this way, what these two so-called friends did is dishonest, rude and disrepectful. You have not really lost anything of value - except for the mount you loaned them.

You have actually gained something from this bad experience, you have learned that the advice Polonious gave to his son Laertes, in Shakespeares' play, Hamlet, is valid. Polonious said:

"neither a lender nor a borrorower be. For loan oft loses both itelf and friend, and borrowing dulls the edge of husbandry."

I never loan money. I do not do work for friends and I do not borrow anything. It saves a lot of aggravation.
