One day, while my mother was sorting things out at home, she unearthed a handful of old calculators (should be expected since 4 out of 5 of us enroled in engineering courses).
With supervision, we decided to let Matt have a look at these.
He looks like he wanted to ask "Ma, why are you taking my pictures?" here.
"WHY?"
"Oh, bother. Gotta figure out how to crack open this one"
" Aha, numbers."
"Mama over there has something like this too."
And he actually said "Hello, hello, Papa" here. Boy, was I caught by surprise!
