When you really are busy, and your STBX is making things like picking up misc things and car registration materials difficult by insisting all communication go through email, and you are on call for the week at work, and so you really cannot set aside some time to "take" them their things with any confidence (could get called, right?), and they respond sarcastically to you saying you are busy.
That sucks. especially when they lived with you for years, so they ought to know you can't play by the ground rules they seem to be complicating everything with.
