My oldest sister, June, sent me a text a few years ago that said "Grandma died. LOL."
Turns out, she had sent that to all of us. She had also posted it on FB. And as it turns out, she had used it several times in texts and emails to co-workers and even her BOSS. And she's the VP of an insurance company, she isn't stupid.
She thought it meant "Lots of Love."
I regret correcting her.
