More on the Politics of Blindness and Charity

So, if people are going to default to the charity model of interacting with blind people, at least when interacting with little me, some questions.
1. In the charity model, is it forbidden to make any personal attachment to a blind person from the designated helper, or is it assumed that if you befriend a blind person and take it past mere anonymous helper droid status, this angers the powers that be or otherwise you are obligated to wait hand and foot upon the blind person?
2. Are help transactions supposed to remain anonymous? If the same helper transacts more than one help event, when is an exchange of names allowed?
3. If the blind person did not approach you for help, and if the blind person is not in any kind of danger, why do they require your help?
There you go, some great ponderances for the ages, O do-gooders.
