Why are they doing this when they made my life a living h*ll back then?

Me and my sisters look a lot alike and we're often mistaken for each other. Here recently they've both been telling me people who thought I was the sister they ran into or asked about me, etc when they made my life pure h*ll back in the day. Asking how I've been, saying hello to me, etc. Like why are you nice now when you weren't back then. Happen to anyone else?
