Do you believe in "signs"?

For example, I’ve been debating whether or not to call this guy… then I happened to click on a youtube video of a girl and her boyfriend.. and her boyfriend’s name is the name of my guy. Then I said, “Ooh, it’s a sign that I should do it!”

Lol, I must admit that it does seem a bit like I’m looking for these signs.

But anyways….do you believe in them?
