WHAT A SMALL WORLD!

Of all places, the ex and the y of Mr Z bumped into each other by the small kiosk in the park--Gaston Park! Both maintained a civil aura as if both had taken a light meal, a vegetarian course, and an anti-stress pill! Whatta small world!
       Facebook is another contributory force of this Small World affairs: You comment about the smiles and the rivets, suddenly, your attention is going to the faces on top and you click and bingo! your kindergarten crush, who is-- right now--a daddy with a tummy! and WHAT A SMALL WORLD!
       Yesterday, I was asking Amorsiko and Emanchelo to go somewhere: away from the malls, mall's benches, mall's benches' smell and other airconditioned spaces! So, we went to Harbor Lights (Irish and Emmanuel, it is with S at the end, OK?). The skies were gloomy but not rain-gloomy! Happy, we were! Mind you, we didn't do the Sun Dance. The place was quiet---for the soul! For a Saturday. I mean, Saturdays are usually big, wild, and strident but when we were there, I was amazed by the silence! The pool enticed the kid of my friend to plunge like a blue whale but the mom gently told the kid about fungal growth and I told him about big rashes and I took off my shirt and said, "Wh--what?Fungal growth?!! Ohshoot!!!" and I put back my shirt. Very effective for the feisty kids! because Amorsiko's boy dropped the subject and played his gadget-games!
       The Small World part is this: Emanchelo, our friend, saw a city councilor. They chatted. We proceeded to the door, going to the garden. It all made sense: The father's son's wife ( in simple terms, please--- the city councilor's wife's brother (I like apostrophe stories! like the neighbor's friend's father-in-law's child is the...anyway, go back to the show!) is the groom of my niece's husband's sister!
     Good luck for the analysis and here's my orange with-cover soap dish for the right answer.
