How long??? (to be read with a very whiney voice here)

Mari Cate:  Mom, how many things do you have to buy at Walmart?

Me:  Mari Cate, if I tell you 5 things and I buy 6 you will get upset at me, so why should I bother telling you?

Mari Cate:  Mommmmm!  How long will we be in Walmart?

Me:  Two hours.

Mari Cate:  Two hours???!!!

Me:  Yeah, two hours....that way if it only takes us 1 hour, you will be happy!!
