"Someone shows up when you are least expecting it." "When you're not looking."
For the most part I don't really agree with that. Yes, when you are younger, that probably is true as there are a lot more single people around - but really after 50 I don't think that is too likely to happen. I used to meet people that way sometimes "when I least expected it" way back when.

When I was in my 20's & 30's & even maybe into the early 40's, that did happen sometimes but considering all the places I go to now such as the grocery store, library, post office, dentist office, bank (places where I am not thinking about meeting someone) but thinking about stamps I have to buy or cashing a check at the bank or going for dental check ups, well it is a myth about "when you are least expecting it" because come to think of it, I have never met anyone "when I was least expecting it" these days.

When I go to record shops and antique shops (my hobbies) I am concentrating on all the folk records I might find that day or antique shops (not always to buy but sometimes fun to browse.) These are times when I am actually not thinking about meeting someone - I am busy looking at the folk albums, etc. - and I guess you might say
"I am not looking" at those times. (to meet someone). But bottom line is even though those are situations where I am least expecting to meet someone - (it does not happen anyway.) I really think that is just a myth or cliché. Or happens when you are young.

Like I said, I did many, many years ago when a lot more single people were around, I would meet people when I was least expecting to - but not for years and years now.
