Who am I?!

Mom: "Facebook has been sending me some other woman's messages! It has my account and her account crossed!"

Me: "What do you mean? what happened?"

Mom: "I've been getting e-mails from Facebook that are written to someone else!"

The e-mails:
"X has tagged you in a photo"
"Y has commented on a photo of you"
"Z has commented on a photo of you"

Mom: "you see? 3 e-mails that are for someone else"

Me: "Mom, you were tagged in a photo, and you get a notification every time someone comments on it"

Mom: "But I'm not in that photo! it's a happy new year blessing. it's someone else's account!"
