Uh oh. Once you go wrong in grandma's book, you're screwed. Looks like you might want to reconsider having accepted the friend request...or maybe redeem yourself, offer her a foot massage or fig newtons...grandmas love those.

My grandma doesn't use facebook, I guess I'm lucky cuz she'd say something similar

Perhaps your grandma mistakenly believes that you are splinter, the sewage rat and she is your nemesis, shredder. That's what I think, and it isn't that she just hates you.

well... that escalated quickly

If your grandma (assuming it is her who replied to you) lashes out like that over a joke, I am sorry to say she isn't worth your time. That or she is becoming senile, and this was a symptom.

This might be just me but I think the grandma is hilarious. Maybe it's just because my family jokes with each other like this all the time but I would've laughed about it and not have been offended at all. I guess it all depends on the family.

And that's why we don't teach the elderly to use technologies :) Nah just be glad that she is capable of using FB.. My mother can't even work FB.

I'm not sure how you are as a person OP, but that comment about the album seemed cocky to me. I'd say YDI.

How many likes?

But was it her or one of her friends?
