Oh for whiskeys sake (my deity of preference currently) this doorstep claptrap is getting more and more ridiculous.
Most of the carers and nurses I know (and my profession is such that I know a looot) think the first time was vaguely nice , now it's just a way for irritating twats to show off , one person I spoke to on Friday practical had steam coming out of his ears because he finds it offensive now.
He actually got screamed at by a family member for going off shift (after 12 days back to back) who actually said "you know I clap for you on a Thursday the least you could have done was stay a bit longer "....honest to whisky.....she actually said that.
And now booing?? Sorry OP but you will get childish because it is exactly that, whilst I recognise it's been brutally hard for you , it does not preclude you from being childish in this instance.
In fairness...free country and all that , fill your boots, for all the pointless waste of time that it is. Get angry , by all means , god knows it sounds like you have more reason than most, but get angry at the right thing not some easily tagged band wagon that happens across your path.
