Just that really!
We moved to this area some 3 years ago, (from 30 odd miles away) and another couple moved at the same time (a few weeks after us.)
We met them in the pub, and they seemed ok for a while, then got annoying very quickly. Nosey and irritating and moany. We found we had very little in common.
We were polite, and spoke to them when we saw them, and we would speak to them when they were at the pub, and we met at a couple of hobby groups. (We only went for the first 6 months we were here.)
But they kept over-stepping the mark; calling at our home unannounced, asking us to do stuff for them and give them lifts, and then moaning to others when we stopped answering their calls, and not answering the door.
So anyway, we finally managed to shake them, and they have not rang or texted us or 'popped in' since April/May! A couple of people we all know asked me in passing 'have you been in touch with them?' and I just said we have been too busy, and we really don't have that much in common, and we just sort of hung around when we first came here as we were both new, and now I have met lots more people, and so on....' People stopped asking about 3-4 months back.
It's such a relief to not have them texting and leaving messages, and I can go in the garden without worrying about them 'popping round.' DH agrees, as he was getting majorly irked with them too.
So anyway, we were writing our Christmas cards out yesterday, and DH said we should send them one! just so they know there's no hostility.... 
Am I being unreasonable to think we should NOT send one? We spent over a year trying to shake them off, and 7-8 months ago, they finally took the hint, and stopped bothering with us, and now DH wants to send them a flippin' Christmas card.
Does anyone think this is a bad/stupid idea? 
Surely it's sending mixed messages? I do NOT want these 2 people back in my life/our lives!
WWYD?
