After two hours we just said bye

I just talked to one of my oldest besties after a long time, turned out she was busy with something and we talked about everything that happened since she was gone, after more than two hours I had to go to the bathroom and sleep so I told her I kind of have to go and she just okay bye, it's very late where she is but she still made the time to talk for many hours it's what I like about her I can talk about anything and she never judges me.
