I'dn't - A sneaky way to say you didn’t do something, even though you

A sneaky way to say you didn’t do something, even though you totally should have. It’s like cheating with words.

I'dn't clean my room because I’m a messy monster.

I'dn't finish my lunch because I’m a food thief.

I'dn't do my math because I’m a math hater.
