I did that to my SO's parents, because they *didn't even try*. That is indeed what I do (just dont respond) when it is rude folks.
My friends have all switched at this point with just the odd slip-up.
The thing I struggle with is the people who actually are trying, but just keep forgetting. And, this group, it is a situation where I often cannot just ignore their reason to address me, (medical service stuff, things are time sensitive, and like, need to maintain professionalism too in front of patients), which is what makes it tricky. And in the offhand, they'll get it right, when there is not the time pressure or such upon us, so I see it more as their mind defaulting to programming. But....it has been almost a year...I feel like at the same time they should be a little further along with their reprograming of my name?
