I had to laugh even harder at this because the same day I saw this, about an hour later (without having seen this) my kids had this exact conversation
(one of my boys is super, super intelligent. His sense of humor is very funny - if you understand all the smarties stuff he draws it from)
10 yr old (yelling down the hall) "MOM! CAN I GO OUTSIDE!?"
13 yr old (correcting his younger brother)
CAN you? Are you capable of doing that? Why don't you go ask mom if you
MAY go outside now, and maybe she will say ' yes', but I don't know if you
CAN. CAN you go ask mom? Are you capable of asking mom? I don't think you
CAN.. I think you're just going to run outside without even asking if you
MAY go out to play. You really should go ask mom if you
MAY go outsiiii..."
Me (getting somewhat annoyed but trying not to laugh) "GET OUT OUT OF HERE YOU TWO!"
