When I crush on people, they're on my mind a lot. I don't act anything out of the ordinary, unless this person is special enough to make me want to take my mask off. In real life, I'm mostly aloof and quiet. But people who I really like tend to bring out the real me, be it a small dose, a large dose or all of da Fluffy. Also, I'll try to talk to the person as much as I can without seeming like a creeper. And if I REALLY like the person, I'll invite them to play games with me. o:
That's all, I think. I see these people in my dreams, put them into my fantasies, and all that stuff to see how they'd fit in with my life. I never go past that unless the person is still in my thoughts many weeks later, because most of the time my crushes on people don't last. I'm too sensitive, especially about rejection, so trying to score a hottie never seemed worth it unless I felt crazy about 'em. I prefer to follow my mind instead of my heart, and my mind is always telling me "Don't even try, you'll regret it." And even if by chance the person could have been "the one", I shrug it off and move on. There was no husband of wife in my future, honestly, because I thought that romantic relationships weren't right for me...
Well, that was until I met the love of my life. I've no regrets about the path my heart has led me today.
