The outdoor thermometer needs a new battery. For the last four days it has recorded the temperature as 45. That’s 45 night or day, sunny or cloudy, morning or afternoon. 

It has me thinking about 45 — the middle-ness of it, its commodiousness. Want winter? Forty-five will do. Scarves and gloves aren’t out of place in the mid-40s. If you live in warm climes and are looking for an excuse to take your wool sweater out of mothballs, 45 provides it.

And yet, 45 can go warmer, too. You don’t need a hat in 45, for instance.  And if you’re moving briskly through space, which I often am, 45 can feel like 55 in a jiffy. 

If your thermometer must be stuck, then, it could do worse than to be stuck at 45.
