Is There A Limit?

Here's a question for you: Do you think it's possible to love someone too much? I mean, not in a psychotic-obsessive way, but like a friend who's going through a rough time. Let me clarify: Do you think it's possible to show someone too much love when they're having a hard time and you just want them to know you're here for them and try to ease their burden. Not love love. That's silly. I've always been a rather soft-hearted person who enjoys showering those I love with gifts/cards/attention. It makes me happy to make someone else happy. But, do you think there's a point of annoyance, or a point where I should feel like I'm crossing a line? I don't know what to think. Of course, an every day thing is crazy, but like once a week to touch base...is that OK? Should there be a limit? Am I wrong to think there needs to be a line drawn? What do you think?
