Me: ...That's okay. You can cry, Sophia. Sometimes Daddy cries, too.
Sophia: No you don't! You're a man. Daddies don't cry.
Me: Sometimes I cry, honey, when I'm sad.
Sophia: Oh. Can I see you cry?
(I fake cry.)
Sophia: Don't be sad, Daddy. I'll hug you...
(There's nothing like a sympathy hug from a three year old to make life a bit more bearable : )
