Three funny stories to share...
One time in my science group in Grade 7, we were all having to take turns reading our lessons aloud, and at one point, for some strange reason, I ended up saying "fer" instead of "for"... I never heard the end of it!
I was once making a joke about how I suck at math so bad that I was "Certifiably 'Mathely' Challenged", and after I said that, an acquaintance of mine then said "And you're obviously grammarly challenged as well."
One time at the Chinese restaurant, I was simi-bragging about how I once killed a gnat with my bare hands (I was being stupid)... the people at the table next to us were the ones laughing.
