I've had an invite for coffee in the new year an old acquaintance / friend (male) who I've not seen in a couple of years. I'm not really interested in seeing him or catching up and don't have much spare time at the moment, so would genuinely struggle to fit it in around my work schedule.
What's a polite way of declining? I'm ND so not very good with social situations and interactions so struggle with phrasing a decline of this kind of thing as well.
