Coincidences related to my sister (half-sister actually)

My name is Maggie. Several years ago, I spoke to my sister (well, technically half-sister) on the phone and said I was retiring from my job. She said she was too. Next time we talked on the phone, I told her I retired on June 2, 2006 -- she said, you are kidding! I retired on that very same day! This with no discussion between us about plans or dates we were thinking about, or anything. I found that very coincidental. Another strange chain of events related to my half sister occurred when we met (we didn't meet until we were adults). She and her current partner were traveling around. She had not seen her (and my) father since she was a small child, so she decided to look him up (with a good deal of hesitation and nervousness). Her partner called my Mom and Dad's house to arrange a visit on this particular day (a Saturday). But -- as it so happened, i had left my husband on the Thursday night before (this was in 1974) and had gone to stay at my parents' house. This was possible because my parents were not home -- they had gone to another state looking for a new house as they were moving (from Michigan to Arkansas). So when my sister's partner called my Dad's house, I was the one who answered the phone. I didn't recognize his name so finally he said, well I am here with your sister. To add to the intrigue, we did not know about each other (not sure why our parents thought it was a good idea to not tell us that we even existed but nevertheless, we didn't know about each other). So to cut a long story short (is it too late for that?) -- he said, we're 10 minutes away. So ..... 10 minutes later a knock on the door; I opened it and there stood my sister! We felt like sisters immediately and have been close ever since. BUT had I not left my husband at that precise time, her phone call to my Dad (our Dad) would have gone unanswered and she didn't even know about me .... so we would not have met. I like to think eventually we would have, but who knows?? I'm so glad I was there. (It was a good long time after that before she met my Dad -- maybe 10-15 years as of course she had been hurt very much by it all, but she eventually did at least kind of/sort of mend fences with him.)
