About 4 months ago I did what my mother told me to do and went and got a flu shot. I wore the band aid they gave till the next day and then forgot about it. Well, about a month later after getting out of the shower I noticed that I had an exact markings of that flu shot band aid on my arm. It was liked it was burned into my skin. Its still there, a tan has caused it to fade a little bit but I fear I might be stuck with this tattoo like marking forever! Arg. Next time, I get a shot I will be bring my own band aids and they will be designer.
