this (technically) isn't '50s/'60s related but

guys

I'm so fucking confused 

So today is my grandpa's (the one who was Elvis's bodyguard) birthday

And my ENTIRE LIFE I was told that he and my grandma were born in 1947, while my mom's parents were born in 1948

But according to Facebook, he was born in 1945???????????!

I'm so confused omg

I'm just like

Grandpa

No

You are not the hoe's age smh

So the way I see it, there are three possibilities 

1) his birth year on Facebook is wrong 

2) I have been liED TO MY ENTIRE LIFE?????

3) We have entered the fucking Twilight Zone
