A former colleague of ours retired a few months ago. However, she's behaving as if she still works here. Every day someone gets a call from her asking what's the gossip etc. She calls in at least once a week with a packet of biscuits and joins us for break, but has started hanging around for ages keeping people from their work or going in and out of offices distracting them.
We went for impromptu drinks after work one evening and apparently she was most put out that she'd been 'excluded'. She's already been reminding us to make sure she's kept informed of arrangements for the Christmas party.
I'm all for people keeping in touch, but usually it's by arranging to meet people they were friendly with for lunch or a drink, not expecting the whole workplace to include her in everything.
AIBU to think she really needs to move on and create a new life, instead of behaving as if she never left the place. I do feel sorry for her, as she must be really missing the companionship of work, but it would be far healthier to join some activities and find new interests. We've tried to work it into the conversation a few times, talking about people we know who've joined a choir, taken up aquavit, learnt bridge etc and how much they enjoy it, but she still seems to see her former workplace as her main social outlet.
