In my three dc's classes we have some of these bohemian, creative lefty parents.. The children are unkempt, scruffy, hair undone & dressed without fail in mismatched clothes... Some of the children have very questionable manners & are either running amock or with their heads glued to screens constantly (as seen on holiday recently, loud obnoxious parents quaffing seccy while the kids were largely ignored).. If council estate kids were dirty, scruffy & looked uncared for social services would be called.. For this particular group (& they are everywhere) the barefoot, scruffy kids are seen as badges of honour..
The lefty parent types are also very anti homework & organised activities outside school as they think kids should be kids however aibu to think they are just lazy & couldn't be arsed putting the effort in?!
