I always seem to hit professional seminars where everyone else has fellow staff members with them and I'm all by my lonesome (flashback to all the years of "first days" at numerous schools as a military brat).
Here are some lines I read and saved a while back. Some seem strange as an opening line, but maybe to keep the conversation going?
1) What was your favourite book/ tv. programme/ film as a child?
2) What is your favourite smell?
3) If you could wake up anywhere tomorrow morning where would it be?
4) What makes you angry?
5) If you could go anywhere on holiday, where would you go and why?
6) What was your childhood ambition?
7) What toy did you always really want as a child, did you get it?
8) If you could do any job what would it be?
