Personal opinion. So ok if the guy is there for terrible reasons that none of us want to contemplate, then yes - bad. There are other reasons why a single man without a child may be sitting on a seat. Did anyone ask him? I worked in a paediatric unit for 10 years, so as you can imagine, people were challenged in a polite way if they were not known family, not staff. I suppose the saddest reason for a single man coming to the unit was that he had lost his child and his wife within weeks of each other. His child died in our unit. Despite a lot of therapy he still was depressed years later. He thought that coming back and being in the place where his child had died would help. So scruffy, slightly drunk, 30 year old man, making a fuss and trying to get into the unit. Handled with sensitivity by the senior nurse manager. Ok - I know this is different, I would also have wondered why this man was sitting in a children?s play area, but sometimes there are reasons for what appears to be strange behaviour that are innocent, sad or complicated. I do feel for men in this day and age. I have told my other half to never walk in any of the parks round here without me or the dog, despite me wanting him to get a bit fitter. Because he is used to being a first responder, so if a child fell over or was hurt he would go and help as trained... I fear that a 50+ Male, on his own, beardy type would be ?classed? as a danger to someone?s child in this day and age.
