In all fairness, that depends on how one describes "friend" and "communication."
I had a friend for like 6 years and we were extremely close like sisters, but a couple of months ago, I was unable to devote all my time to her, as she expected, and I wasn't playing that game. She got angry because she called me twice and I simply was not available to come to the phone and I was not going to feel guilty about my boundaries and explain myself. At times in the past I would tell her I'm sorry I missed your call, I was doing blah blah blah. But we don't always need to explain ourselves because it's then the people sometimes take advantage and see that as weakness. But because I didn't answer the phone when she thought I should, she assumed I was avoiding her and so she decides to childishly punish me. Well she sees that doesn't work. I didn't answer the phone because that genuinely could not. There's a million other things that can be going on, but since I didn't answer the phone then I did later send her a text that I care and I hope she was having a good day. Followed up with the scripture to encourage her. Well she was still mad because I didn't answer the phone so she ghosted me and here she was supposed to be my best friend. She didn't write a response for two months. She wanted me to miss her and feel guilty but I was having none of it. As I mentioned, I don't play those games. Then to give her the benefit of doubt, I texted her with another kind message of encouragement, she answered very very briefly which was fine, I answered back, but I guess that wasn't enough and she ghosted me for another whole month. Seeing how important I was to her that she couldn't even wish me a happy Thanksgiving, or even bother to acknowledge me or answer me at all, I felt she was still punishing me in her own way, so I blocked her. Now she doesn't have to worry about me not being the friend she expects me to be. I don't feel guilty about it. Actions speak louder than words. I feel I did my part.
And then you have those "friends" who are not respectful of your time, don't even ask, but will keep you on the phone for hours upon end if you let them. Boundaries are so important and people should respect each other's boundaries, not impose and not get angry if someone can't stay on the phone a whole two or three or four hours. That's not my problem. If they think it is, then that's her or his problem. We teach each other how we want to be treated and it's not right to take advantage of people. Sometimes we can stay on the phone a long time but other times it becomes a problem and we should be able to lovingly express that without people taking offense every time we can't talk long or can't come to the phone. Yet someone to take up your whole day if you allow it. First try to resolve these things but if they cannot be amicably resolved, it's time to let go of toxic relationships.
