A few years ago,I moved to Aurora,Ont.with my boyfriend and I longed to make friends in my new neighborhood.
Where we lived the hous were jammed together so tightly.But the irony （讽刺） of living so clo was that no one actually talked to each other；as in an open-concept office,they pretend they can't hear or e each other to maintain at least an illusion of privacy.
It was not so easy to make friends as an adult.I was about to give up when I caught sight of a beautiful,tall blonde taking out her recycling.She walked with confidence—even her ponytail bounced.I gasped, "I recycle too!We have so much in common!"
The question was,how would we meet？What would I say？So I thought, "What if I just happened to be jogging by？" I put on my running shoes,but after a few times around the block,dripping sweat,I didn't e her.I decided to ize on the one thing I already knew about her— she takes out her blue bin.
The following day,I woke up a little earlier than usual.A little after ，the garage truck appeared and the blonde emerged.I grabbed a bin and made my way to the end of my driveway. "Just act natural,Megan," I told mylf. "Good morning.How are ya？" I said,
cool as a cucumber. "Good.And you？" she replied. "Doing well…moneyballI am a new comer,just a DJ.I talk for a living.Clearly!" "Interesting," she said. becau of you原唱
As we both walked away,I turned and called out,"Oh,and by the way,I'm Megan." "Michelle," she replied.I walked back inside,wearing a giant grin.
Our "coincidental" recycling meet-ups continued for a few weeks until I finally gathered my courage to ask her to watch The Bachelor with me and she said yes.
That night,after we got everything ready,we ttled on the couch and proceeded to drink wine,binge from our buffet,disct doomed television relationships,tell stories about our own and laugh our faces off.We "found what we'd been looking for"：a new friend to fall platonically in love with.
