Hello Brain!

We were folding clothes and I suddenly asked 哥哥 to spell a word, again ...

哥哥 : Huh? Why that word again?
妈妈 : Because you cannot remember. That's why I'm asking you again. Can you try?
哥哥 : Cannot.
妈妈 : Why cannot?
哥哥 : Because my brain is not working.
妈妈 : Hhhuh? Not working? Then how to to make it work? *giggling*
哥哥 : Got to knock on my head and say, "Hello brain! Are you working?" *and he went on to do it*
妈妈 : LOL So is your brain working now?
哥哥 : Yes, I think my brain wake up already. Working now.
妈妈 : ^_^"
