Write a card to an awkward relative you can't ignore

Write a card for an awkward relative.

Occasion: [details]
Why it's awkward (high level): [details]
I still need to send something: [yes]
Tone: [civil / lightly warm]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. A civil sendable card message.
2. A slightly warmer option if safe.
3. Fake intimacy lines to avoid.
4. Whether a group-signed card is wiser than a solo essay.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, quotes or what the other person thinks. UK English.
