This will probably attract some bilious responses , but try to get in in perspective.
The shite who do this type of thing lead appalling ,sad, wasted, pitiful & usually short lives. They will probabaly never experience true happiness, love, affection & respect ( in the non street sense of the word ) from those around them.They are unhappy & distressed & probabaly have nothing in their lives to look forward to - no travel, no new experiences, no fulfillment.They will never be comfortble with themselves ( not financially ! )
Your son on the other hand obviously has a caring family & is sensitive enought to work out what is going on . In a few years he will be older & better informed to take a direction in life of his own choosing. In 10 years, he could be doing whatever he wants, whilst his attackers will still be wasting their days & lives with the same old wankers, taliking the same old shit, hanging with the same old shitbags in the same piss smelling pubs & eking out a pitiful and worthless existance.
IN the big scheme of things, this is a minor incident, however bad it seems at the minute.
Im sorry if this sounds smug or patronising, but I am a working class male for a rough part of the North East. I know what is like - I escaped & went travelling as soona s I was able * never really returned - I had seen too much.
I go back some 20 years later & for the shitbags, nothing has really changed in their lives, expect they are older.
