Where's the logic?

Jonah is sort of funny sometimes. Today him and my mom talked about how he cannot wear his favorite shirt to school anymore because it is a bit too old. The is so disappointed and starts begging my mom to let him keep wearing the shirt. Of course my mom says no. Not even 2 minutes later Jonah yells down to Jacob "Jacob! Look at this cool move I can do!" Jacob responds with "cool Jo". Only Jonah comes back saying "yeah too bad it will cause holes in my sock... oh well." Where is he logic???
