You'll never get the hint. You two will drop hints to each other until the day you both die alone. What a waste! Is it so hard to say, "I'm free let's do something"? Yes! And that is why you will never get together.
You're an adult but for some reason when your crush is around you, you no longer know how to form sentences. They are in there, in your head but it's impossible to get them out. It's better to never talk to them and just run. Run far, far away!
You spent two hours getting ready knowing that there was a slight chance that you could possibly, maybe, possibly, maybe run into them. Then you do and...nothing. You get a simple, "Hey" if you're lucky. Whatever! You look good and he doesn't know what he is missing. I HATE HIM!!!
Why is it that every time your crush is somewhere in the area your life becomes a mess? Whether you fall over yourself or you have an entire salad stick in your teeth, it's just not a good look. Just try to keep it together.
You see on Twitter that they are home alone, so naturally you drive by their house. Then you drive by again and again and again and again just praying that they will come outside and "run" into you. You're not stalking; you are being protective.
Ah yes, the good ole bully tactic. You don't know how to communicate with someone you like so you just treat them horribly. You give them a complex for the rest of their lives and they end up in therapy wondering why no one ever liked them. All of this, because you liked them. A lot. Good job!
You know everything about them, even though you've never had the courage to talk to them IRL. How then? Their Twitter and their Facebook. Just make sure you don't reveal too much if you ever have a chance to talk to them face to face. If they know you've been stalking them online, it's going to freak them out.
