My mom tells me this story all the time.

I was about 3-4 yrs old and she was trying to teach me to say "Yes,
please." Also "No, thak you."

One day I'm sitting at the table eating some cookies and she asks,

"Brian, would you like some milk."

I just noded my head.

"Brian, say yes please."

I noded my head once more.

Kind of fluster my mother says, "Brian you have to say Y-E-S
P-L-E-A-S-E."

I finally opened my mouth and said " I'm not s'possed to talk with my
mouth full." Spewing cookies all over the table.

Moms are good at that... Gosh.. I've even done it to my Kids...
