Support turns up in an order nobody predicts.
People you expected to be there sometimes go quiet — not from unkindness, usually because they cannot bear it. Meanwhile someone from the edge of your life, a colleague, a neighbour you have spoken to four times, starts putting your bins out on Sunday nights and never mentions it.
The useful kind rarely asks how you're feeling. It arrives with a specific offer: I'm at the shop, what do you need.
Count the odd ones in. The circle is usually a different shape from the one you thought, and often wider.
