@Lestat, the problem is, we'll be watching the DVD of the Live At Wembley Stadium, and we'll probably be singing/lip syncing, etc. I don't want Staci to feel left out or anything, and I for sure do not want a fight, or in this case, probably a situation where no body talks and it's all awkward. It won't be like that if it's just Ashley and Zoe and I, we're better friends, more similiar when it comes to interests, and we're also insane and laugh at the same stupid stuff.
@Rav, nope. I can't think of any similarities.
And yes, Staci is probably the most mature (and sane) of us.
Well if she's the more mature just warn her from the beginning you're going to goof of like the adrenaline drunk crazy fans you are and that she eithers goofs along or keeps quiet... in a slightly jocular tone that conveys that the underlying message is serious but without offending her. phew.
