Thank you so much for your words! Instead we thought of USA as a magical unreal place where is impossible to go and which exists in movies. In fact my first time in the US (even though it happened recently, more than 20 yeas after USSR collapsed) I did feel like in a movie :)  Little things which americans are used to, were remarkable to me. For example,  when woman who was selling  snacks called me ma'am :) Or  those diners you have with music machines. Damn, actually I left and never tried one!
