Me too haha. I've seen that too. You don't really even know the person, how can you love them? The only time that I can really think it'd be okay to say "I love you" in a short amount of time is if you had just gone through this adventure or scary matter and were alongside each other the whole time. Seeing that type of thing in dramas/movies I can understand more than if the characters just met and they haven't really been through anything, haven't really experienced much together - but suddenly they start to like them. Saying "I like you" is more reasonable than saying "I love you" after that amount of time. "I love you" is something more intimate, I never understood how people claimed to be in love after a day or a week. How do you know you're in love in that short amount of time? That's lust not love haha
