Five that end it
- "Haven't met anyone worth the trouble." Cheerful, complete, unarguable.
- "Busy year." True of almost everyone, and nobody follows up on a calendar.
- "I'll let you know when there's news." Warm, and closes the subject without a snub.
- "I'd rather hear about you — how's the new house?" The question back is doing the work.
- "Genuinely happy, thanks." Said once, lightly, it lands. Said twice, it sounds like a defence.
Why the honest answer backfires at a table
A real answer invites a real conversation, and a real conversation about your love life at a family lunch is a conversation you did not choose to have, in front of an audience, with someone who will bring it up again next year.
The considered reply also reads as an application for advice. Give an aunt three sentences of context and she will supply the fourth. A short answer denies her the opening without being cold about it.

It is usually not really a question
Most of the time it is small talk from someone who has run out of small talk, or affection expressed clumsily. It is not an interrogation, however it lands, and treating it as one raises the temperature of a room you have to sit in for another three hours.
The exception is the person who asks repeatedly, in front of others, after being answered. That is not curiosity, and you are allowed to leave the conversation, change tables, or go and help in the kitchen. Walking away mid-sentence is a complete answer too.
If you would rather not field it at all
Some women book company for exactly this reason — not to imply a relationship, but because arriving with someone changes the shape of the whole afternoon and the question mostly does not get asked. If that is the plan, what you tell people about him is its own small decision, and one worth making before you arrive rather than at the door.
Either way, the arrangement is yours to disclose or not. Privacy is respected on both sides, and nothing is recorded or posted without permission.
Frequently asked questions
What if they keep pushing?
Repeat the same short answer once, then change the subject or the room. A question asked three times has stopped being a question, and you are not obliged to keep supplying material.
Should I just lie?
An invented relationship has to survive the whole afternoon and the follow-up next Christmas. A short true answer needs no maintenance, which is why it works better.
Does bringing a plus-one stop the question?
Usually it changes it — people ask about him instead, which is a much easier conversation to steer. What you say about him is entirely your choice.
Isn't booking someone just avoiding the question?
It is choosing not to spend an afternoon defending your own life to relatives. That is a reasonable thing to want, and it is strictly platonic company either way.
