I don't have a problem in things coming up in conversation where a person says, I did this or I did that. But when used as a platform, like the person I mentioned in this post did, a justification of their worthiness or validity...it's something I find repellant.
Promoting a cause one is involved in (done the right way) can be productive promoting oneself and what one has done instead of the cause itself is selfish, egotistical and repellant.
That's the thing, the right way to do it, because it might attract more people to help, but where there is no egoism and not for the sake of doing it to be looked at.... a lot of ego.
