There are people out there, like myself, who don't use social media. Perhaps that's the case with OP

Fml is social media ;)

But the sister may not use it

She could not want family on her page. my little sister has me and a few other family members blocked and she lives with us.

I have my facebook set up to not send out birthday notifications.

Not everyone on FB makes their birthday public. I don't let anyone see my birthday on FB except me. I'm old enough that my birthday isn't a big deal to me, and I don't want to spend the whole day hitting "Like" and typing "Thanks!"

While I agree that the sister has more right to be upset here, you don't seem to realize this is probably an FML because of guilt. OP likely feels like shit for forgetting, and you coming along and being a sarcastic tool about it doesn't help.

op SHOULD feel like shit for forgetting, 0 sympathy

Wow they forgot a birthday no big deal

One person forgetting it is one thing, but her whole family? Including her parents? Inexcusable.

Maybe the family didn't make a big deal about birthdays before this, or maybe they all were busy with other important things and it slipped their mind.

If you're busy to the point that you forget your own child's/sibling's birthday, you need to do so reprioritizing of your life.

You said "hard on".... huh-huh-huh....

Are you JW? (Actually wondering, as they don't celebrate anything but anniversaries)

I did grow up as a JW and it sucks. We left it when I was about 12 but I had never had a birthday party or ever been to one. It did really suck a lot, especially in the fall when you had Halloween, thanksgiving, and Christmas and everyone was so excited and you couldn't celebrate any of it. Whenever the class had holiday parties I had to stay in the library and couldn't participate

I think that's pretty awesome. I have everyone's birthdays and other important dates written down on a wall calendar (as well as notifications on my phone), since I know I wouldn't remember them otherwise. You're lucky! :)

It's definitely unusal, but hey, it's a nice talent to have. I need to program everyone's birthday into my calendar, or I'm not going to remember them.

My sister has that too

Thanks for replying, guys! I was genuinely curious if it was just me. And it's just birthdays too; I was terrible at dates in history class and I couldn't tell you the exact date I graduated high school. How strange!
