When your Asperger's son is deep in adolescence, it's sometimes hard to tell whether their behaviour and conversation is more autistic or teenager. Two examples below from (extremely intelligent) Son1:
Son1: Are you saying I'm fat?
Me: No, it's just that I need to put my office chair down and I don't have the weight to push it.
Son1: So you ARE saying I'm fat.
Me: No, but you're five inches taller than me and therefore heavier.
Son1: I know you think you're 5' 3" but you're not. You're 5' 1". Which means I'm seven inches taller than you.
Me: Deep sigh.
Son1: What's this suitcase doing at the bottom of the stairs?
Me: It's your suitcase that I've been asking you to take upstairs for the last three days.
Son1: No you haven't.
Me: Yes I have, ever since you got back.
Son1: No you asked me to take my CASE upstairs and this is a suitcase, so I didn't know what you were talking about.
Me: Slaps own forehead.
