The context of the following conversation is Alex had to stay late and missed the school bus, so Alex walked home from school one day.:
Alex says Trust me it's a walk that you don't want to make..
The friend responds How long did it take you?.
Alex responds It was over an hour in the snow..
The friend responds It wasn't cold though..
Alex responds Thankfully it wasn't, if it was colder out I would have had to call somebody for a ride.
The friend responds You should've done that anyways..
