My son loves Dr Seuss... I read one every day. Though his favourite seems to be "Are you my mother." and then throughout the day I am faced with "Are you my mother? Oh you are my mother" with a giggle attack followed.
I often find that I have to have an even amount of things. If it is an odd amount it can drive me insane... Like if I buy some kind of house decoration I buy two just so I can have things even... perhaps its because I am the only odd thing I want in the house ;)
