['I was eating breakfast when my daughter screamed, There a humongous spider behind you!', 'Oh man, that would have freaked me out what did you do?', "I thought there'd be some huge tarantula, but it turned out to be just a tiny little thing. I caught it and let it out outside."]
It seems your daughter may over exaggerate things a little bit.
My daughter screamed because there was a humongous spider on the kitchen floor. It turned out to be a pretty small one.
