We're at the playground.
My girl (pouting at a small dark patch): Papa, is this bird shit?
Me (sitting from afar): I don't know, but does it look like bird shit?
My girl: Not really but I don't know.
My boy: Wait let me check.
He then uses his finger to mash on the small dark patch, and proceeds to smell his finger.
My boy: Nope, it's not bird shit!
Argh super pek cek!
