Dear Batman,
Thanks for taking care of the Joker. Dude was messed up.
Also, thanks for cleaning up your room and remembering to brush your teeth.
I miss the days when your punches said "Pow!"
Someday I will miss the days when you hugged me in
front of all your friends.
Are you getting any royalties from Batman (TM) licensing?
I owe you fifty cents for weeding in the garden.
Please don't speed in the Bat-mobile.
And don't be in a hurry to grow up.
Don't forget to take your Bat-belt (TM) with you where 'ere you go.
And please remember who you are and that your parents love you.
Love, Mom
