I don't understand why you would volunteer if you think you will just stand in the corner not talking to anyone. Honestly, an event that needs 1000 volunteers is probably so big and busy that if you see your T at all, it will probably be at a distance and hopefully you'll be so busy that you won't really have time to think about it.

I wouldn't worry about whether you see your T or not. Go into this event in the true spirit of volunteerism and throw yourself into helping at the event with a passion.
