Next time you have people over for dinner, everyone should wear pj/sweats/loungewear.
Then, you should serve breakfast/brunch for dinner.
Of course, it’ll be necessary to eat said meal with mimosas.
Afterwards, round out the evening by playing games like Taboo and Scattegories and proceed to roll on the floor (or foam play mat) laughing till you cry, over, and over, and over again.
Finally, make plans to do it again real soon because life’s short and it should be spent having fun more often than not.
