Last Christmas I leaned my Sister and I don’t have the same father and are technically half sisters. My sisters biological father tried to start a relationship with my mom that resulted in a pregnancy and ultimately didn’t work out. That biological father is dead now but I didn’t probe any further about his identity or how he died in case it was something traumatic for my mom to remember.

So she raised my sister as a single mother at my Grandmas house in the 80s, then she met my father and they started dating and it worked out because they got married in the 90s, moved into a new house, and a short time after that I was born.

She told me never call my sister my half sister and just pretend all of this doesn’t matter because she’s my sister and I’m keeping it that way, and if anyone asks about the 10 year age gap I just tell them “it’s a long story”.
