When I was younger I used to think the word 'birth' was rude and I used to hate it when people would say it. So basically, I thought 'birth' was a swear word. I laugh at it now but I think I still have a problem with the word...In class once (when I was younger) the teacher gave us a little education on babies and said the word birth like 15 times and I cringed every time. I had such an issue with the word. I hated it so much.
It's so stupid but I don't even know what drove me to think that way about the word.
