As for some saying, I can't give time to people, I don't want to listen to their problems, I can't be bothered with making friends, most people are toxic and just use you, well yes if you think that you won't have any friendships. Friendships do listen to EACH OTHER, I spent a whole unbroken half hour, more or less, ranting on the phone in the car at school pick up yesterday because I needed to, it was my turn, I obviously do the listening as well. But even in my ranting I was trying to make friend laugh and when I did let her get a word in she managed to squeeze in a paragraph of advise that was gold dust and I really needed so I feel better now. But that gold dust wouldn't have happened without the previous 15 minutes of solid whinging from my side. So I texted her later and said thanks that really helped me out. Because it has and I appreciate it.
I'm one of them. I don't mind occasionally listening to venting but not all the time, with so many people it's one thing after another and they want you to listen to all of it. It's never "my turn" because venting doesn't help me. I don need that from a friendship. They won't be able to help me, because I don't need advice, I generally need practical help of a kind others are unable to give (on a friendship level). I pay for that help. So venting isn't for me, if I'm going through something I want fun times as a distraction from whatever it is.
What have you got to lose?
Hours of my time listening to others issues, which upset me and takes over my day worrying about them. My sanity, because listening to the same issue over and over from someone who wants to offload as a way of enabling them to tolerate a shit situation is incredibly draining and misery inducing. My entire day's supply of energy, I don't have much unfortunately, so I want to spend time with friends having fun not swapping miseries.
It's not toxic for you because for you it is a two way thing. For me it isnt. I'm generally considered to be a good listener and good with advice and support. So I attract people in difficult situations who want that from me. I'm not saying all people are toxic users, I've nothing against most people, it's the situations I often end up in that are toxic to me because they're so one-way. I have in the past had long standing friendships with lovely people. But times change, people move away, you enter different life stages, your paths diverge etc and friendships don't always last. That's ok, it's part of life. Knowing that this happens, I prefer to be choosy these days, to be without hardly any friends than to have the wrong ones. To put my needs into the equation, instead of accepting friendship from any Tom, Dick or Harry (often with issues and wanting someone to vent to).
I agree with the rest of what you said though.
