I agree and feel the same way, however, by "tooting" you are also encouraging others to follow in your steps. Don't think of it as bragging because if it was you would have quickly been called out on the carpet. Sometimes it is wise to share these experiences with others. after reading they might be able to see the need of others in a more clear manner. Just think of how the world would look if we all got into a "help those in need contest" to see who could out do the other. I sometimes think that if we made a bigger deal out of some of this "Selfless" giving that we might have more of it. it's usually the small stuff that means the most so don't be looking for a "change the world" idea...just find someone hungry, cold, or lonely and do something simple...
My 2 cents...if someone chastizes you for "tooting" ask them when the last time they had something to "toot" about...just guessing it will be a short conversation.
Keep giving!!! Even if you never see it come back it feels so good!
