Co-worker:Wow Serious Child that's fantastic you got an A on your progress report!
Serious Child: Thank you. Mom was happy but I don't really like school that much.
Co-worker: Well for a kid who doesn't like school you sure do do great work.
Serious Child: (shrugs shoulders) I guess.
Co-worker: (giggling) Did you hear what I said, you do do great work.
My co-worker and I then high-fived and giggled to each other.
Co-worker: Do do? You heard me right?
Me: Totally. That's why we are friends. Serious Child you don't find this funny at all do you?
Serious Child: No. You two are weird.
He then promptly walked away leaving us still giggling at do do and the realization that an eight year old is more mature than us. Whatever, he's missing out on the fun.
