So, even though I only have a couple of followers, I'm still going to say this (partly because it happened to me and I don't see it often enough) and hope it reaches most people.
If you EVER think about asking some (as a joke/prank/dare) to be your Valentine/girlfriend/boyfriend etc., don't. I repeat, DON'T. Even if you're pretty sure that they don't like you, just don't it can still hurt, way more than you think.
I'm saying this out of experience. Less than a week before Valentine's Day, the guy I've liked for 5 years, asked me to be his Valentine. Now, he was a good friend, and I was pretty sure he knew I liked him. But the way he asked me, I believed it was a joke or a dare, that it wasn't actually happening. When I asked him about it a few days later, he said it was a joke and my heart shattered into a million pieces. I knew it was too good to be true, yet I still believed it. When I told my mom about it, I cried. I hardly ever cry, much less infront of my mom, but I couldn't help it. I felt as if my whole world had crashed down that moment he said it was a joke. I cried myself to sleep that night, and the night after. It still makes me cry to this day, over a week later, and I have a feeling it'll make me cry for many weeks to come.
I can hear people telling me right now as they're reading this, that I shouldn't cry about it because it was a joke, instead I should laugh, or just not think about it. But I can't, I wish I could laugh about it, but it was a moment I've been dreaming for for 5 years, and it finally happened, then turned out to be some stupid lie. One of my friends even yelled at me 'because it could be worse.' Yeah, it could be worse. Some people out there lose their spouses etc. and here I am crying over some joke. This is the worst pain I've felt, so to me, this is as bad as it gets.
Guys and girls, don't EVER ask somebody to be your Valentine etc. as a joke, because it hurts. Even if you know 100% that they don't like you, it still hurts.
