It happens with many kids who are actually introvert type and the feel odd to move in the town after 7:00 PM, it is basically a psychological factor. I am really happy that you and your wife made a plan to go for a walk

We went for a walk near a nice place close to our house to talk about it more.

P.S: By the way 124KG is not too much but you really don't seem obese in your photographs
