I certainly didn't have it my way when I was living it

You, my dear, have earned the right to remember it how you like.

I just am cautious about going on about how good we had it, because that's unfair on the young folk. My nephew grimaces at that, and I get it.

It is rude, thoughtless and filthy.

Same goes for cigarette butts (you aren't allowed to smoke on the beach here, though I've never seen it enforced) and any kind of rubbish including flytipping.
