Me and dh often talk about this sort of thing, We get the impression we are treated differently by professionals because we look young.
Dh is 26 i am 24, were married and have a comfortable life however when we go into hospitals or see 'professionals' we feel like we get shrugged off as being erratic or to young to understand, 2 examples..
Dd was 8 weeks old she had been crying for hours and something was just not right with her so i went to the Dr, she told me i was being stupid and that Dd was just doing what babies do, refused to check her over and sent me on my way saying she would tell my health visitor im not coping..
The very next day Dd was worse so i went to a&e and i found a lump, was in an ambulance with a groin hernia within half an hour taken to leicester hospital many miles away. We were told if i had found the hernia a day later she would of died.
Another more recent example.. i was in hospital and dh went to ask a nurse to take my canula off the machine so i could change from the clothes id worn for 2 days nearly, we waited 2 hours and he asked again before he was leaving the nurse told him there was more important people than him..
dh aunt pops to see me, she's very middle class and well to do type last she asked and they did it within minutes.
It does seem that certain people treat others with disregard, and there is a massive divide with class and people going by appearance when judging someone.
