The last time I had a crush on someone was 8 months ago, so I'm a bit unsure of how to answer this. Maybe it's when I start feeling giddy around them? When there's that ticklish feeling in my stomach just from talking or interacting with them. When I can't help but notice every little detail about that person, when their presence excites me. What I feel is... I will start having this constant urge to keep talking to them all the time. I might ask them any kind of question and blabber quite a lot just to start a conversation, or even initiate spending quality time with them. There's also this urge to impress the person, to make them happy and feel comfortable around me. It's typical, I think. Just like how a regular person would act when they have a crush on someone.
