Nate's favorite day is Monday. Every day he asks me what day it is, but if I tell him it's, say, Thursday, he corrects me. "No, it's Monday!" So when Monday does roll around, he is overjoyed.
"What day is it?"
"Today is Monday."
"Oh thank you thank you thank you thank you!!!!" (No amount of exclamation marks could overstate the 2 year old excitement here.)
What will he think of Mondays in, oh, 20 years? We shall see.
