You know that feeling you get when you see your favourite toy or ice cream flavour? Well, having a crush is sort of like that feeling, but instead of a thing, you get those same butterflies in your tummy when you see a person you really like.
It's like having a big secret that you can't tell anyone- except maybe your best friend- because you don't want anyone to tease you or make fun of you.
It's also like having a really good daydream where you imagine yourself having fun times with that person, holding hands or kissing, even though you know it might never happen and it's just in your imagination.
Having a crush means that you might feel nervous or shy around that person, and you might sometimes feel like you can't control your emotions when you're around them.
But it's also an exciting feeling because it means you're starting to have feelings for someone special, and that's a really cool thing to experience.
