I think Covid has put a strain on "friendships" & whether we realise it or not it might have sorted out the "wheat from the chaff." At my age I only have a small group of friends and have felt dismayed that it's me who sends the text to ask others "Are you ok? How's things?" There's then a flurry of texting but that's all. (I can't make calls - hard of hearing).
After a time lapse, sadly, nothing spontaneously back the other way. I'll wait until we are allowed normal life again & if I'm not contacted I'll let things go. Won't bother & sail through life "friendless!" In my humble opinion, friendship should be a two way street.
Luckily I'm self contained & can accept & enjoy solo life so it'll be interesting to see who, if anyone, pops back into my life. I hate the fact it seems to be a one way street but I can live with that.
