I swear Isaac is turning into a teenager.  The other day he said "Gabe, I am so mad at you right now!" because Gabe beat him to the bathroom.  Then the next day I was trying to get him to take a nap and he told me, "You're not my friend anymore!"  He also tells me to get out of his room because he doesn't want me there anymore (again, when I'm trying to get him to take a nap or go to bed, lol).  Crazy boy.  It's so funny.  Can't say he doesn't express his emotions.
