Not knowing you... I am sure it is heartbreaking for Valleylady as she invested a lot of time and effort into the sponsorship, I used to volunteer for the said charity when I first came to Goa and back then I think one of the children had 13 sponsors and most had 3 or 4, I don't know if that's still the case, but I am sure it can't be easy for the children meeting and remembering all these people.
Scarves.... The lady has always been a little bit forward when asking for things, that's why why do so well in getting people to sponsor their children.....
Bag's being dumped in the corner.... We occasionally receive clothes from supporters and generally it' easier to look through them when everyone has gone, as it takes a lot of room to sort the clothes into ages and girls and boys, although it's always polite to ask if that's OK..

Gifts... I don't think the other children would bully her for the gifts although it can be difficult to give just one child a gift (however small), we have the same policy of not singling out a child, if you want to give something for the children then you should give something smaller for everyone, rather than a bigger item for 1 or 2... Either that or give for the top ten best attending or for prizes for best work etc, something which they can all strive for. Looking after larger groups of children you have to treat them fairly otherwise it's another reason for them to be sad, and we're here to make them happy!
50 children in a room 30 ft - 10ft..... According to the children's home rules each dormitory should have 40sq foot per child, so if you're right then 50 children in that room is not good, however sleeping on the floor is considered relatively normal here in India, I do it actually, I've got a double bed at my apartment but choose to sleep on the floor, tends to be cooler...
children go home to mumbai, when the tourist have gone.... When I volunteered there most of the children went home for holidays at the end of the school term (which is at the end of the tourist season), most of the children are from out of state, Karnataka, Marahastra etc but I as far as I am aware they only go for a month and then return, I think most are from faimlies who reside in Goa, or have done at some stage (bt I could be wrong)...
As Robert and Carol said, it's always best to visit to make up your own mind before supporting a charity, we're not all the same....

Thanks
