I went to a women's avalanche safety class in December. (SAFE AS) All the coaches are female athletes who perform at a high level.
I walked in to the registration area, and there was Sherri McConkey, doing pushups. "Sorry - we have to do pushups if we apologize." I laughed and said, "I guess you're going to have to do ten more!" Honestly, I don't think she even noticed she said it. It's so ingrained.
Recently a friend told me she has to steel herself to not apologize when telling a developer about a business decision not to use the dev's preferred toolkit.
It's hard wired into a lot of people - especially female people.
I have noticed that, and in particular the gender balance thing. Culture certainly plays a part too--I don't know how true the stereotype is, but there is a stereotype about the British that they will apologize for you pushing them down.
Most of the unnecessary apologizing I see comes in through the contact form on my website, where quite a few people seem to use "Sorry to bother you" as a salutation, which is where the apology jar comes from. It seems to come from a sense that, because I am in charge of this free service, that there is somehow a social hierarchy at play at so one must apologize for intruding upon my valuable time. This feeling honestly makes me intensely uncomfortable and I hope that the apology jar will encourage people to stop it. It makes me happy that people value what I do, but it makes me uncomfortable when people seem to defer to me for it. I prefer to be treated as a peer rather than a superior--respect for a fellow human being, but not deferrence.
I provide the contact form as an obvious conduit for interaction with anyone who has a reason to want to reach me--that's what it's there for. If you knock on my door uninvited, then you should apologize for that, and then you should go away, but you don't need to apologize if you take the public route of communication which I have myself put in place to make myself reachable.
Maybe it makes people uncomfortable when I ask them not to apologize, but I hope any discomfort is worthwhile in moving toward a place where we can all just talk on equal footing and not feel the need to defer unless that deferrence is somehow necessary. :/
Anyway, this is all a tangent away from the story topic, obviously.
