The post below got me thinking.
How far does biology go for equaling family? Someone in the below thread said, more or less, "Whether or not she raised him does not change the fact that she is his bio-mom and has a place in his life".
Posters get told all the time that it's ok to invite in circles and it's not necessary to invite blood relatives that you don't know well or at all.
Is there a point re: certain family members that regardless of relationship, because they are blood related they should be invited?
Sorry this is vague, but I'm trying to be discreet.
