So what is love?
If I wanna be all factual and daft, I guess I could say it's a set of feelings felt towards a person or persons. It's the people who I care for, people who I can smile at even after an argument, people I feel attached to no matter what. We are social beings so we need the presence of others to survive. And thus, I think, we would do anything for the people we love.
To illustrate this a little better and make my boring post a bit more interesting

, here is a quote from the main character of the story I am writing, since this basically sums up my opinion about love. This is his promise to his little brother:
"Look, Sheol. I'll never abandon you, as long as you don't want me to. There's nothing I wouldn't do for you. If you asked me to count all the stars, I'd do it for you. If you wanted me to drink an ocean, I'd do it, for you. And if you asked me to go to the end of this endless world, I'd die trying, for you. Because if you are my motivation, nothing seemsto be impossible."
It's basically just a bunch of phrases, but it goes well here :)
What is it that makes you think that you are loved?
I feel I am loved when people act in ways the older brother would, as mentioned above. When I mess up and I am forgiven. When people surrender their own satisfaction for mine. A simple line "What's the matter?" means a lot, especially when I know it comes from someone who genuinely cares. And the best is to be loved by people who don't neccessarily have to tell me they love, for me to feel it.
What are the limits of love in your opinion?
The only limit is that what I am incapable of doing. However, as we haveall agreed with Ryan that if one wants, they can achieve it, this question beats me a little. I'm not sure ifI have enough experience to be able to answer this question.
Are there any acts which a person who loves in incapable of performing? In the sense that if these acts are done, then they are evidence that the person didn't or doesn't love.
Yes, I would consider deception and betrayal such an act. Sometimes people get blind when they love someone and they tend to ignore the fact that this love is being unappreciated and unreturned, even ridiculed.
Can love disappear with time? Is it changeable?
I guess it depends on the kind of love. However, if love is unconditional, then it shouldn't ever disappear, right? Maybe in that case we just try not to act upon the feelings, if we decide that the person we love is not worthy of our love anymore? Tough one to answer :S
