Wow. Even my 6-year-old can get his own lunch cooked. My 8-year-old made everyone California rolls and smoothies for lunch, last weekend. Sad that your kid won't attempt a Cup Noodles or something. (Not sure who the "better" parent is... you for actually feeding your kids and fostering the expectation of regular board, or me for making them fend for themselves so often they have learned to cook.)

An 11 year old is old enough to make a sandwich or some chicken nuggets in the microwave. They are also old enough to understand how work can cause you to be tired. If your child doesn't know how to do any of these things or understand these concepts yet, you need to sit down and have some conversations already!

At that age I was cooking for my family.

****** punk ass kid, throw pizza on the ground and tell him to eat with his granny

What the grandmother must be is her dads mother, and in turn, doesn't fully trust her daughter-in-law, and has said something like, "if something goes wrong call grandma and shell be there"

She should know how to make a sandwich at least.

At 11 she should be able to make a sandwich or cup-of-noodles.

Maybe the 11 year old just wanted mom to make DINNER. The OP seems to be doing something right, having family dinners together. It sounds like this 11 year old was just a smart politician, not necessarily a kid who could feed themselves.

If I had tried that when I was younger there would have been hell to pay after grandma left.

That's sad.. at 11 he/she should know how to fend for himself/herself.
