Every year my teen DDs go a fri-sun camping trip with a club they go to. They love it and look forward to catching up with people they've met in previous years.
This year the fri of the camping trip falls on my 40th birthday. I'm not planning a huge celebration but would like to organise a family meal out with my parents and siblings. Would it be awful of me to ask them not to go camping this year to accommodate my birthday? I genuinely have no clue if this is unreasonable or not?
