redefining "tough"

Me: Hey Alex, what do you think of the new shoes I got?
Alex: Are they for me?
Me: Um, nooo...
Alex: Can I try them on?
Me: I guess so.

Alex: These shoes are scary.
Me: They're scary?
Alex: Yeah, 'cuz they're really tall.
Me: Your dad's reaction when he sees you in those shoes is what's going to be scary.
Alex: But they fit me!
Me: Sort of...you can get your feet in them, I guess.
Alex: Hey, I can walk in them, and now they're not scary anymore!
Me: They're not?
Alex: No, because I'm tough!
Me: Yeah. You're tough.
