I hate the way that language like this is so normalised around kids of his age. The poor lad stands no chance.
The 6 year old lad is watching his Dad, who is his world and learns life lessons off, calling a person out who is simply doing his job. Fat Divvy D**kh**d etc etc. I hate it. It really makes me cringe. If you don't like what the steward is doing, just be civil. Its really that simple. Also more likely to get a better outcome. Not sure that would give you the views on social media that people crave though eh.
Like these videos where kids say swear words and that, seemingly out of nowhere. It snot from nowhere, Its learnt behaviour. The child is either picking it up off the parents or something the parents are allowing them to watch unsupervised.
I might be in the minority here, but swearing is bad manners, and kids shouldn't be taught bad manners.
I'm in my 40's and I still don't swear when my Mums around. Had I of sworn in front of my Nan, well Holy Christ himself would have to make an appearance.
