surprising repetition, friends, family, boyfriends, kids of friends have shared the same birth date as my kids and family but i have never met someone ever that has my birthday (only know of but have never met) birthday coincidence's; father...boyfriend/friends; mother..my great nephew her great grandson; brother...my best female friend of almost 40 yrs; sister...another best female friend of over 25 years;my oldest daughter...my great nephew, kid of old high school friend; my second oldest daughter...her cousin from dads side, my ex brother in law, kids of old high school friends; my youngest daughter...kids of long time friends; all of the above...coworkers "work friends" and two long term relationships that both had the same birthday but different years, these SR's are a running theme my whole life and still happening. i also identified with similar life line with one of my bff's mentioned above, we have a 17 yr age diff, me younger and a boyfriend met later in life raised over a thousand miles away from me, born same year had same interests growing up and experiences both personal and social. simultaneous events i can also relate too.
