At least you had ice cream :)

"Beauty is in the eye of the beholder"

Well you're in the right place to "eat your feelings". Ice cream makes everything better!

Should have said "well at least I can get a hot date, instead of talking to randomers in an ice-cream shop". Then dropped your ice-cream cone on the floor like a microphone and simply say "served" before walking off.

he was probably jealous because he wanted your friend.

If you're a guy and you're friend's a girl, it might just be a sort of non-threatening way for him to pay her a compliment while pointing out he wasn't actually trying to hit on her (he acknowledged the "date") but also not trying to hit on YOU. I hear these kinds of comments from male friends/relatives of guys I date all the time, sometimes even from the guy himself, sometimes even, like here, from total strangers.

That's cold

How rude!! Disregard OP, feel good about yourself..

You should have retorted, what I look like can be changed, your personality, however, cannot.

Ignore rude people. Looks change. They can fade. a bad personality tends to last.
