Bedtime.

Casey, calling from his bed: Mummy, one more cuddle and kiss!
I go in, and give him a cuddle and a kiss.
Casey: Five more cuddles, mummy, and five more kisses!
Casey (counting my kisses): 1.. 2.. 3.. 4. 1.. 2.. 3.. 4. 1.. 2.. 3.. 4.
Me: Okay, that was 12 kisses.. time to sleep now.
Casey: No, it hasn't been five kisses yet, it was only four!
