Being a jumpy weirdo.
This kid jumps at EVERYTHING. So do I. He's never actually scared or upset...just jumps about a foot and makes a hilarious face.
So, because we're mean, almost every night when he's sitting with us at the dinner table, one of us makes ourselves burp just so we can see him do it. Usually he laughs after, I promise. He just thinks the camera is weird so won't smile when it's out.
