I tried to keep a serious expression when explaining. I've always thought abuse and cheating should be the only reasons to get divorced. Other things can be worked out. Needless to say, he got somewhat emotional and began burying his head, not saying a single word for a moment. It took several times to tell him it's just a prank.
I got that idea from a divorce prank video on youtube I saw a while back. I want to grow old with him. I was just joking.
