Calder went on an outing to Bishan Park yesterday and I decided to check on him by texting him. As usual, he video-called me when he saw I was online.
Me: Hello Calder!
Calder: Hello Mommy!
Me: Where are you?
Calder: In the living room!
Me: Are you in the living room?
Calder: No!
Me: Where are you?
Calder: At home!
Me: You are at home?
Calder: No!
I realised that Calder was giving my whereabouts, not his own location, so I modified my question.
Me: Where is Calder?
Calder: At Macdonald's! (Right answer.)
I just realized that Calder does not understand "you".
