For me, it’s ‘All you have to do is ask!’ It’s gotten to the point where I’ve stopped asking because the response is usually the same: ‘I’m unavailable’ (even though you know their schedule is wide open) or ‘I forgot’ (even though the forgetfulness is unintentional).
The end result is usually the same: you start to feel like you’re invisible, so you stop asking. That, in and of itself, leads you down a whole other road that people don’t see and it’s one that you don’t feel like explaining because it would take more energy than you have to do so.
