are u actually sorry

When someone tells me they are sorry I believe them at first but then I get to know them more and they lie about being sorry so when they say sorry again I doubt the fact they might be lying but when I say sorry it depends on who I'm talking to if I'm talking to a close friend I will mean my sorry if I'm talking to a enemy I mean there won't be a sorry out of my mouth if it's a stranger that I don't know I wont know if I mean it or not but now a days I can't tell if people mean their sorrys which really sucks I'm starting to convince myself I should only say sorry to people I care about try and change my mind but don't think u will
