fun with sisters

texting conversation
me: Did you know that you can't stick your tongue out all the way and breathe fast at the same time?
Sis: What?
me: Stick your tongue out all the way and try to breathe really fast.  It's impossible.
Sis: I think this is a visual experiment because I am breathing just fine.
me: Haha but do you look like a puppy? :)
Sis: Haha I hate you
