A few years ago my brother, who is 7 years younger than me and was about 10 at the time, found my tampons and came running in to ask me what they were. Here is how the conversation went:
My brother - Hey, what's a tampon?
Me - What do you think it is?
My brother - (sniggering) Female condoms
We've never let him live that one down
A childhood belief about periods

others believed things like this
- My brother that is 6 years younger than me used to believe that in seven years he would be older than me.Anon
- When my brother would go by condoms i thought that guys had period and that is what they usedAnon
