Double-date is a beautiful way to find maybe another part if your heart or simple boyfriend or girlfriend. When boy or girl because of some reason can't go to normal date (maybe he/she thinks it's so shame or I don't know) he/she can take a friend and tell his/her date-partner to do the same. So it looks like two boys and two girls on one date. Little fact: in more more then 60% of double-dates girls take the most ugly classmate or so as a friend - just to look more nice in comparison with her. So it's all right to gonna double-date if you afraid (or so) of normal date.
