My views have been tarnished a bit by my Mothers experiences, she used to send money to just about every charity that pushed an envelope through her door not even questioning the dubious and sometimes badly spelt claims in the packaging. Before long she was receiving requests for money daily, but luckily she is reasonably ok mentaly so ignored all the "you have one a prize" offers because she doesnt do competitions, but would still send a tenner to any name that she recognised, especially if they gave her a free pen to write the cheque with, and wouldnt accept that some of them may be fake.
The true scope of this didnt become apparent to me until she moved out for a month to have her flat refurbished and I saw the mountain of mail she had been receiving piled up in a corner so finally managed to get her to stop.
As the requests for money started to dwindle the genuine charities started to ring her up, sometimes bordering on being a bit agressive, but their requests fell on deaf ears, literally (97 years old and wont wear her hearing aid) so now she lets me vet who she sends money to.... or at least I think she does...
Personally I think Children in Need is a good thing and am amazed how much money is raised, but the entertainment is not up my street so I dont watch it..
After all viewing isnt compulsery and the TV does have other channel buttons...
