What's something new you learnt about your partner lately?

On Friday night, I went to bed later then my bf did. When I joined him I thought of something funny and started to giggle. I guess he was half awake and he asked what was so funny and I thought I'd play a trick so I said "the clown" and he asked what I ment and I said " the clown over there" and I pointed to the chair on the other side of the room. He shot up, fully awake and was breathing hard. Turns out he's petrified over clowns and that's something I never knew. It was hilarious the way he shot up.
