Friend: "Do you want to go swimming in the weekend?"
Me: *Thinks about it and then remembers how patchy head is* *panics about wet hair and visible patches*
Friend: "Well...?"
Me: "Ah no thanks...I have this....thing"
Friend: "Oh, time of the month?"
Me: *-_-* No.
Friend: "Right...."
A/N: This has happened so many times, like i'm too paranoid to have my hair down let alone wet.
