There is a risk the lady isn't pregnant at all and you offend, or if she is pregnant, it will make her feel very self-conscious about her changing body shape. If she is pregnant, let her tell you when she feels comfortable. Most couples don't share their good news until they have their first scan around week twelve.
You want to be at the front of the gig? Good. Get to the venue early and queue up like everyone else. Don't wait until the gig has started and then push your way through the crowd to the front - especially if you end up hurting people, knocking them over and splitting up people who want to be able to enjoy the gig together.
So you've joined a gym. Good for you. But before you go in there and attempt to pump any iron there are some things you should know. There are rules they don't include on your membership form or on that bit of paper that asks if you've ever injured your back or had an allergic reaction to Lycra. I'm talking about social rules, gym etiquette...
Recently, I found myself involved as a "Twitter expert" in a "radio debate" about swearing on social media. It went so well that they missed out publishing that week's show podcast and I said "sir" live on air, which while it isn't a swear word, is a feature of my speech that really annoys me that I'm trying to eliminate.
Certain happenings of late have got me thinking about etiquette. Take for instance the sorry state/lack of genuine "Hey, good morning. How are you?" in the workplace or the mass disruption of the tube strike by the RMT and TSSA unions. Better yet, a fellow journalist being trolled for getting Vincent Vinturi's "rape manual" eBook removed from Amazon.
Public transport is a common method of travel by many people across the globe, yet somehow some people still haven't mastered the art of getting it right. We have people that seem to think that they are the only one in a rush to get to a certain place, that they are the only one on the tube or that nobody around them has any transport requirements.
I always wonder why it is that audiences boo. Opera audiences can get extremely cross about interpretations of their favourite operas, especially the classics. I'm more concerned with the need, the irresistible urge even, to be outraged by a director's interpretation and to give voice to that frustration.
One thing is for sure - saying thank you is a nice thing to do. It makes you feel good, and makes the receiver feel valued. We may not subscribe to the hand written parchments of old, with ruler straight lines and wafty words of gratitude penned from inky quills, but we do still subscribe to basics of liking to give and liking to be thanked.
