It’s Sunday afternoon. Oliver is out with his University of PEI peers participating in a downtown scavenger hunt.
My phone rings: it’s Oliver, making a Google Duo video call.
Oliver: I am so hot!
Me: Where are you?
Oliver: I’m downtown, in the park by your old office.
Me: What about your water bottle?
Oliver: It’s empty.
Me: Okay, look in the corner, over by Richmond Centre; you will see a blue water fountain with a water bottle refiller. Go and refill your water bottle.
Oliver: Okay.
I happened to know that there was a water fountain there because I added it to OpenStreetMap two months ago.
All kinds of interoperating technology FTW.
