Poor bloke. 
I used to know a man who was not even that short really - 5 ft 6 and a half. He had 3 brothers who were 6 ft 1, 6 ft 2, and 6 ft 3. He was royally mocked all his life by them, and the dad who was 6 ft 2, (and called all kinds of short person related names!) And other relatives and neighbours and family friends and colleagues took the piss too. Him having tall brothers, (and a tall dad,) made it even worse for him (than it would have been if he had just been a man of 5 ft 6 and a half - with no tall brothers and a tall dad.)
They were relentless about the 'short-arse brother.' He was never as successful in life as them, and was a very insecure person who never became a high achiever. I do wonder actually, if it was because he was a bit on the short side for a man, or because of all the mocking and deriding about his height. I suspect the latter.
My grandfather was 5 ft 4 and a half inches, and a very successful businessman, who was never short of attention from the ladies. (Much to the annoyance of my grandmother!) A bit like Mike Baldwin from Coronation Street. Mike was only 5 ft 5", but was a successful businessman, and never had shortage of attention from women!
And my cousin (female) is 5 ft 0, and her DH 5 ft 3 and a half, and their 3 sons are all 5 ft 4 to 5 ft 5. All very good looking and successful professionals, with very attractive wives. (one of them 3" taller than him, the other two the same height.) So being a bit shorter (as a man) can affect his life, and success at work, and his ability to form relationships. But it doesn't have to be that way if he can battle through the mocking, and just get on with his life, and try not to let his height have any affect on anything.
Easier said than done I know!
