Way back when, before social media, a woman I considered a new close friend had a baby the same month I did. We swapped babysitting and hung out at each other's houses.
There were digs and snide comments and outright criticism of very minor choices like baby products. I was so desperate for friendship that I didn't confront her or push back but got increasingly bothered and annoyed.
There was also a one sided competition and lots of comparisons like developmental milestones.
Life happened, I went back to work, created some distance. Friend reached out and we had a play date for old time's sake at my house. Shortly into our time together my friend decided to discipline my DC about something ridiculous while I was in the room.
That was it. I don't miss her.
