Just that really. Happens to me all the time. Silence for months (literally didn't reply to my happy birthday message) and then "Hi! How are you? Can you still get discounted x?"
Or another one who has had many years of one-way cards and birthday gifts out of me, but silent for last 18mo until "I'm being made redundant can you forward me any jobs at your place?"
What do you do with these people? They're perfectly nice but is there any point? And has anyone successfully converted them into thoughtful reciprocal friends?
I do understand lockdown has been weird for everyone. I'm hoping that's the reason.
