You know I never noticed that Black Men don't say "bye" until like 2-3 years ago.....
I say bye on the phone out of habit cause my mom always say bye, so I was raised to do it.... So I kinda find it rude when someone doesn't say bye... I'm used to it now cause none of my homies say bye.... But my white friends say bye, and girls i talk to say bye.
Every now and then I meet girl who don't say bye, but I think it's cause she been dealing with a rude ass nikka who too manly to say bye to a woman... which I find gay.
