How to fight back? His ex girlfriend got offended by my harmless joke :(?

[HedyTiew]

There is a 17-year-old guy who looks like a 20 plus guy for everyone. I posted on his Facebook's wall saying that "I can't believe that you're only 17. You look so matured." And his ex girlfriend got offended and commented this *points below*

"well,i've known him for like yonks and he honestly is 17..and no joke bout that brah...he's like full on 17 cause like you know,me and him are like tight as...also i even saw his I.C....ain't no doubt bout him being his age and he doesnt no...t bloody look older...cause you do know if you call someone old it's like heaps offensive....
like seriously..just accept the fact that he is 17 and just sick with that cause he aint older than 17...too childish to be older than that too..."

What should I answer her back? She just took it so serious wth. Thanks for your help xx.

haha noooooo. Sounds like she is the jealous ex. Ignore her comment or come up with a witty remark.

Tell her to calm down it was just a joke or just don't answer

be a jerk to her. itll make the world smile. tell her you are appreciative that he has her as his walking, talking birth certificate. that loser! tell her to get a hobbie... or a myspace.
