The context of the following conversation is Sasha struggled to get their sweater on since their hair was just done, so Riley pulled the wool over Sasha's head.:
Sasha says I spent so much on my hair, I didn't want a silly sweater to ruin it for me..
The friend responds But it's part of your outfit right?.
Sasha responds Yeah, that's why Riley came over and did it for me..
The friend responds He's such a nice guy isn't he..
