When my kids were still that, and they asked me what my favorite animal was I used to tell them it was a slug.  It was for no reason except to gross them out and be silly.  We would laugh and giggle, and they would repeatedly ask me “Daddy what’s your favorite animal?  It’s not really a slug”.  I maintained my composure their entire childhood and always answered “a slug” with a straight face.  I realize the photograph above isn’t actually a slug instead it’s a snail, however, I thought about my kids when I saw it and smiled.  And I guess now they are both adults I can finally stop with the subterfuge, it’s snails I really like.  And I love you both dearly.
