I don't have one on me as I know I wont need one, carrying one around with you means to me,
1) you are in a realationship and you are going to have a sneaky one out and about.(im not in one at the mo')
2)you often have one night stands (not for me thanx)
3)you have a feeling that the person you have been interested in for a while is going to say or do the right thing that night.
4)your not planning on going to your own place where you have a stack of them!(Id rather go back to my place, then I don't have to leave)
;-p so no condoms on this chick.
