That saying sounds good but it's not always the case. There's some people that I've stop talking to and I don't talk about them period positive or negative. So no I don't believe in that saying for every case although it dose happen in some cases.
Not always true. Sometimes people just grow apart and that doesn't mean that they are a bad/fake person or going to talk bad about you. I stopped talking to my best friend just because I didn't like the person she was becoming/being...but I do not talk bad about her or even talk about her at all if I do it's just about something we did together awhile ago. Me and her haven't spoken in months
