We can converse with the peapod now. She mostly responds by saying "OK" when she agrees and refuses outright by saying "No No No".
When P was onsite, I used to drive the peapod to church on sunday. During our 10 min drive, I would tell her she is not supposed to make noise within the church or play in the church, ok? and I asked her to repeat ok after me, which she did. She started responding to ok? with a "ok" and soon realized that she was agreeing and was not allowed to go back on her word once agreed. These days "ok" comes after she has thought over it. So now when we say "ok?", she takes her time to think and then agrees or completely ignores it.
We have a Tam Brahm family staying above us. A sweet old couple. They love the kids and often call after them from the window or the balcony. Y/d we were on the swing when aunty called out.
Aunty: peapod, I am going out. what do you want?
Aunty: How many?
Aunty: which color?
Aunty: what else do you want?
Aunty suddenly wriggled her nose as an instant reaction and continued what ele do you want
peapod sensing something is wrong: fisshhh with a smile
Aunty wriggled her nose once again and asked "do you want chocoloate?"
peapod with a dimply smile to tease aunty again" Fisssshhhhh"
Aunty: I dont like fish, do you want chocolate?
peapod: "No, fissshhh"
So there is a sense of humor somewhere in there. Thank God.
