Friendship points

I have this strange notion that I have "friendship points", that I accrue when I either a) have left a friend alone for a while or b) I've helped them out in some significant way. Don't get me wrong - I don't keep score, and I don't help out my friends with the expectation of anything in return. BUT I do feel bad if I ask for help from my friends too often, or if it's something really big.

An example is moving help. I think you can ask any friend at maximum twice in five years to help, with the promise of free beer and pizza as minimum compensation. The ironic thing is that I only consider asking for help when it's a big deal and I've exhausted most other options (makes sense, right?) and since I really hate asking my friends to help with things, I end up feeling really bad about it.

One of my friends has suggested that my notion of "friendship points" is ludicrous, that it doesn't work that way among true friends. I think true friends (BFF!) are hard to come by, and that managing "friendship points" is crucial until they reach the upper echelons of friendship. And here is another post with an awkward ending.
