Stop in for a cup of coffee

My dad walked out when I was 5. Didn't see him again until grandpa's funeral when I was in my 20's.
Well I've posted this along with most of my past here before.
Dad would send me across the street to my mother's supposed best friend who I believe my dad liked but, she wasn't interested in.
At 13 she decided to give me a private birthday party.
Started with a glass of wine and then a few beers. Today you would go to jail for that. All in all no complaints I learned a lot.
After I started talking to my mother and that didn't last long. She told me how she never contacted me but kept in touch with her friend who was taking care of me..
When I said sure was and that part was mutual.
Took a bit for that to Register with her.
