My brother T and my sister-in-law L are visiting from Canada (Sept. 29-Oct. 2). It’s been awhile since they’ve been in Brooklyn. Certainly more than a decade, but for busy-ness, this period of time has few parallels in life. Now, though, all our kids are grown, and needing us in different ways, so during our visit to Canada in the summer (See Running for Your Life: Canada!, posted July 28) T asked what weekend would work best for them to come visit in the fall, which turned out to be the one in brackets above, a week before my birthday (Oct. 5) when the tourist buzz at Brooklyn’s TKTS is down to a dull roar so that reasonably priced seats can be had for even high demand shows like “Billy Elliot” and “Anything Goes,” L is fine to go along with whatever during the weekend, enjoying everything in equal measure but she’s the one who picks Billy Elliot, so on Saturday morning T and I do the hunting and gathering, snagging a couple pair in the mezzanine, which for a dance extravaganza like BE was just the ticket, because it was an amazing show.
