Well, once you get chicken pox, you never get it again, I've heard.
Actually it is possible to get it twice. Just that the chances are low.
Here's my story.
I was the average, Pogeymanz freak 3rd grader, when we were having Physical education, I noticed this big spot on my left Fore-thumb, I was interested in Medicine at that time. I thought it was a mosquito bite and I decided to trick someone.
So I came up to this dude during free time and said "Hey, I got Chickenpox!"
He didn't look impressed, he replied "Oh really, does it have a dark spot in the center?"
"Nope"
"Does it itch?"
"Like you can't imagine"
Next thing I knew, he ran away so fast, he looked like an Olympic Platinum Medaller.
Later the coach called me in asked if I was scaring kids with chickenpox. I said "No, it's a mosquito bite :3.... I think"
She then referred me to the nurse just to be sure. Then it turned out I actually HAD chickenpox. Oh the horror, that one a One Weeker.
3rd grade was my worst year. I got my glasses that year as well.
