@Tes yeux noirs,
decades back, there were a couple of fellows who would call me - and then have nothing to say
I hadn't called them, wasn't interested in talking to them. I was bored by them. My life was plenty unboring outside of their calls.
after a couple of minutes of me trying to make polite conversation I used to ask why they'd called. if they basically said , "to talk to you", I'd find a way to hang up semi-politely.
