I did. It was actually pleasant seeing them. My trepidations were largely unfounded, and it was actually nice seeing all my siblings (except my late eldest sister) and step siblings in one place at one time. I don't think that's ever happened before. Seems they had no inclination to mention life on that farm either. My step-siblings were 5, 7, and 9 years older than me, and both step sisters were already married and away from home. I'm the youngest of four stair-step kids, meaning our stepbrother was only two years older than my oldest sister, so we had a pretty large group of siblings at similar age.
My eldest stepsister who lived near Mobile (Bayou La Batre) used to make a lasagna every Thanksgiving that would make you slap your tongue for having too much fun. I would eat lasagna until I got sick. Unfortunately, I think she's in progressive stages of dementia and very poor health. She lit up like a Christmas tree when she figured out who I was but was staring at me again about 5 minutes later with no clue. The middle stepsister, whom I thought I'd never met swears up and down we did when I was pretty young, and living at the farm, putting me between 12 and 18. She lived in Long Island, NY, so seeing her would have been pretty rare, at best. However, there are some parts of my life on that farm I choose not to remember, and that meeting may have happened during one of those times. I have a lot of long blanks between 1970 and 1976 that are best left blank. The shindig happened at her oldest daughter's house and was a pretty big soiree. Her oldest daughter also remembered meeting me, though she would have been just a tot at that time, and again, that intentional amnesia thing. My stepbrother was very nice to see again. He and I were pretty close, probably closer than my own brother, because we shared a room during my first and his last year on the farm. Hard to not get to know someone you share a room with. My brother never moved to the farm with us, but I wasn't given a choice. My stepbrother was drafted in 1971 (I thought he just volunteered) and joined the Navy but in that year and many times when he came home on leave, we fished and hunted together. I think it was him who gave me my first beer on one of our fishing expeditions on the Tombigbee River. Fishing/hunting with him was a lot more enjoyable than doing either with his dad.
So, overall, a pleasant experience to see them all. My stepbrother lives in Texas, but both stepsisters live in Mobile, so maybe we'll do it again.
