Другу: Hello my dear friend! After the party last weekend I am not able to find my pair of jeans.This is weird, really, but I don't remember how I got home… Can you do me a favor and look for my jeans around the house? These are really expensive pair of GUESS jeans and I paid a fortune for them (around 150 bucks… ouch!) Thanks in advance! Cheers!
