Your friend complains that her boyfriend forgot to get her something for Valentine's day. A cold response:

This is consistent with both your current boyfriend's previous actions and your previous boyfriends' actions. You should spend some time thinking about why you seek out romantic partners that consistently disappoint you.

A warm response:

Aww, that sucks, I'm sorry. Hug? Wanna go look at pictures of kittens on the internet?
