To make a move or not

That is the question. Makes me wonder if it's a part of some ancient ritual. If it is please come up with a guide book. Anyway... The reason for the title is simple. I have gone out with a group and this one girl is around a lot. We flirt, but not regularly. It seems to come and go in spurts. Some time she throws hints and at oter time she seems to be in a whole new solar system. So now I ponder the age old question. Who knows, but one thing is for sure. I better have my head on straight come cruise time. For you see she is one of the 6 girls going. Seven if you count the gay man.
