The world is small

...and full of surprises. I know, this is a well-known truth, but how surprising is that: my mom goes to this gym (well, in our town we have only one), and the other day she met there a lady, with whom she started an interesting conversation about different things - mostly, I guess, it was about exercises, diets and healthy lifestyle in general :D
And then, it turns out that this lady was my literature teacher from high school! My Mom spotted her name on the list in the gym when she was leaving - and she has known her only by the name, from my stories told at home and from formal meetings for parents at school. So they never met on, let's say, informal grounds. And now, many years (because it's not just "a couple" anymore) since I left school, they seem to become colleagues! What a coincidence...
