ever heard of Byron Katie and her "The Work"? it's basically an approach to see a "problem" situation from a different POV. 

what if what you're "dreading so" was a totally joyful experience instead? what would "magic" (or mischief) you need to bring to the day to make _that_ your outcome? "what would this be like if it _wasn't bad_?"(TM)...

I'm not suggesting that you engage everyone in all-day rowdy poker hands, but perhaps try _something_ no one expects and everyone will enjoy. be the one who shifts the tone, who heals the mood. amaze yourself. and your relations... 

 I like your suggestion but I’m at an event so I’ll just grin and bear it 🤙
