about friendship

I have always been of independent character. That doesn't mean I do not depend on others. Only that when I do, I try not to impose on them. Except probably my couple, but I do not want to go into that possible flaw of my character now.

What does this mean?. I think friendship is something given freely.
Like open arms or a hug.

I have (and have had) some friends who have told me I was not there for them. But they didn't say that something was happening. I was supposed to poll them at all times to ask them if they were ok. Except I had my own problems. And I would have been there for them at no time. But they have to call me.

I travel for long times and get isolated for one reason or another. If you want me to reach you, you have to ask. I do not give more than I ask for. I will not reproach a friend for not contacting me while I was in a bad shape.
When I need help, I shout.
