I was raised old fashioned, strict parents, belt whoopins, manners and being polite. I always hold the door for anybody nearby in general. Ive tried teaching my kids the same but there are a lot of rude people these days. Grown folks older than me that wouldnt even respond when my 8 or 10yr old sons say excuse me or hold the door open. Im sure by the time there grown, it will be against the law or it will be offensive. Safe spaces for all.
