Did you ever became friends with peopels you never even imagiend you can talk to?
I have some guys at my base. They are truck drivers (Ill give you all non-IDF soliders a hint - you dont have to finish high school to be able to join and fit in this job, or have a clean crime recored, or know how to write your name). So one day,i passed thier room and there i see one of them play World of Tanks. As a fellow player i watched for a while, then asked him what tank he use and etc. Next think i know Im already in THIER clan and we talk daily.
