I've never been in a stalker situation, really. But I see it happening all the time, its especially popular in movies. Of course, those are epic, and getting stalked for real is annoying. I can imagine the constant messaging of:

"I LUV UUUUUUUUUUU!!!!!!"

Or...

"I know where you live... and I love you..."

Or even...

"I like pie. Do you?"

Okay, the last two are a little less heard of, but I swear they're legit! (Mostly...) But if I ever get stalked with the creepy "Have you checked... the children...?" type message, I know what I'll say...

"I ate them."
