So yesterday my cousin called m, but I didn't get the call( one I was sleep two it didn't go through) So anyway, I woke up and got on Facebook made a comment her sisters page and then she text me and tells me (oh you posting on fb but can't call me back) So I call her to explain I never got a call but she doesn't answer and pretty much blows me off. So today I happen see her post a quote about some crap of don't make ppl priority who make you a option. So I'm like where do ppl do that? I didn't even avoid her like its totally a misunderstanding !!! Like what does matter, why are we as people so dang stupid and inconsiderate. I'm just not understanding😶😶😔
