In 2018 my sister got married and we had their wedding in my parents backyard. Of course during this time, we spend a significant amount of time with my sister's fiance's family. We saw them once in 2020 - for an outdoor socially distanced small gathering but not again since. We will be getting married in the summer of 2022 and I'm trying to decide if I should invite my now Brother-In-Law's parents.
We've seen them approximately 2-3x since the wedding, mainly for events hosted by my sister or for my brother in law's birthday. His parents live an hour north of us and they live an hour south of us - so a common meeting place for his birthday to go to dinner is right near us so sometimes they will invite us.
My mom (to my surprise) said we don't need to invite them - but I'm second guessing if they should be included.
I'm not sure what the proper etiquette is on this and we do still have space on our guest list. That being said - my brother in law's father is a fabulous wood worker and we're hoping to have him and my brother and law help with our wedding arch and or custom corn hole boards for us. Also why I think it may be important to invite them.
Thanks!
