Deaf 耳聋

Benja said hi to a worker at the construction site, but the wirker did not respond. Benja told Mummy, "Uncle 耳聋 (is deaf)."

Taken aback by the rudeness, I asked Benja who used that word. He told me it's Grandma Marzuki.

For a second, I was glad that it wasn't Ah Ma who taught him this word. But the next second, Benja continued, "爷爷耳聋 (Grandpa is deaf)。"

I couldn't believe my ears, so I asked questions to confirm that I didn't hear wrongly.

Benja said, "是, 爷爷听不到, 爷爷耳聋。 (Yes, Grandpa can't hear, Grandpa is deaf.)"

Omg!! What else does she say to my Benja??!!
