I have a friend whom i talked to everyday for past few years and suddenly he wants talk on schedule like only om friday,saturday and sunday, is this considered normal friendship?
I had a friend like that. Sometimes you just exhaust the topics you want to talk about and would rather focus on other things than just talking for the sake of talking.
Going down to a schedule might just be his way of making time for you while also getting other things done. Or maybe he just doesn't feel like he has much to contribute and would rather wait until he has something to say.
Keep in mind the possibility If that friend needed something and thought you could be of assistance they’d not be using a schedule to communicate with you. As well you should find out what this schedule thing is all about.
Friends that make time for one another do we'll, however this would have to be done with the Grace of knowing that not all days/dates will be achieved. Both of you need to be ok with that.
