I am guilty of always being on the point of ringing someone, but always putting it off. then they ring/email me.
Then doing COVID, I was very slow about ringing a friend I had been due to lunch with the day the lock down started. I kept putting it off and she did not ring me. This went on for a year, to be fair, DD was critcally ill then DH hada heart attack,
Then I got a phone call that she had died suddenly, although she had been unwell for some time. I was devastated. Now, I do not worry whether people contact me or not. I make contact with them, Yes, of course i am not perfect and some do delay, but I get round to it far faster than I did.
