My husband and I have been invited to a charity auction dinner. I don't want to go as it's a midweek event and (we have very busy schedules) and I don't want to feel forced to bidding/buying items in the name of charity when actually we are tightening belts. It's a professional event so giving b as an excuse isn't really an option.
How do I politely decline, do I give an excuse but also request to see the auction catalogue out of politeness and show enthusiasm (then just never bid), or do I just give a flat no.
It's the second event I've said no to the same person so I want to do this sensitively and not to rule myself out of future events, because I otherwise really enjoy their events and company!
