I think I saw my sister while on vacation.

Iím currently on a Ukraine ski trip with my significant other when I saw her. We stopped by the city to grab some supplies and I saw her walk towards one of the malls. It definitely felt surreal, just seeing her after nearly 7 years. She had a big fight with our parents, which prompted her to move out and break contact with all of us.

I mean we were never really that close, but I still care for her. I kinda miss having her around the house and having someone to talk to about my problems. Should I try to find her? Or would it be best to just leave her be?
