English killing vs tamil killing

It was so funny yesterday.  Ashwin wanted to sing but every time on his third line aishu would cut in. She didn't mean to annoy him just she couldn't help but join in but he wanted hos airtime and was getting super frustrated. 
I tried telling baby to take turns bit she wasn't getting it. He was getting g madder trying to sing at top speed but she'd still cut in on line 3. He started trying to lunge at her saying I want to kill her aatha. Not the tamil killing but the English killing!  I was just laughing.  Then we moved to the room where aishu was lying on the bed and he was still mad and trying to attack her when she screamed like a karate fighter contorted her little face and pulled him down by pulling on his shorts. He fell on one knee and started crying! I had to run to the other room to laugh. I thought the little one needed protection but she was completely able to defend herself!
