I think he’s right
I think she’s nervous
I think I like this
"We are not done here... I think you need another one..."
I think this counts
I think these qualify?
I think this qualifies
Good morning, I think
It feels so good not to think
I think he died
I think this counts
I think I'm alone, but I hope I'm not
I think she looks kind of like Professor X's not-girlfriend
