Depressed

Pi
We were invited to our neighbor kid's birthday party and we went there. Many other people are also there but all of them have kids. It's only us who are not having any kids and I felt very sad about it. But all the while we are smiling and tried to mingle with the group. All the mommies out there talk either about there kids or about what they've gone through during pregnancy. I have no experience of all that stuff and just sat silently listening. I felt so out of place.Maybe I should have avoided going there. I don't know.
