Lately my son has missed out on 2 birthday parties that his classmates have been invited to because I was not Facebook friends with the students' moms. I am only on Facebook to connect with very close friends and family and do not use it as a social pathway for invites and social gatherings. My son has been directly affected by this though, because he hears all of his friends talking about how much fun they had at the party when we were not even aware of it. When I asked another mom if the invitations were sent home she said they have both been a Facebook invite. Do I need to become friends with the other parents so I do not risk my son getting his feelings hurt from missing out, even though I do not know them?
