xX_RolePlayer_Xx asked me for "crush advice".

Oh hohohoh! This is going to be FUN! For those of you who have a crush on someone, LISTEN UP!

Now, this is going to sound like the corniest thing EVER, but it is the truth! The best advice I could give you is BE YOURSELF.
"But Mettaton, what if myself isn't good enough? My crush won't like me!"
Darling, if your crush doesn't like you for who YOU are, then they are absolutely NOT worth the time. Imagine spending the rest of your life with someone who you can't even be yourself around. Isn't that just horrid?!
I understand that it hurts, but it's all part of growing up. That person you dated in middle school probably wasn't going to end up being your future husband or wife anyway.
Trust me, there is someone out there for you. You have a future that shines as bright as me! (because I, of course, am LIVING MY DREAM!)
Going through a few heartbreaks is all part of learning who you are, especially when you are a teenager. Ah, I remember my teenage years.

Let's never talk about that ;)
