An ordinary weekday becomes an anniversary the moment something big happens on it. Any day could be the one.

Dates are not special in advance. A Tuesday in March is nothing in particular until something lands on it, and then it stays marked for everyone involved for the rest of their lives. There is no way to know which of the next thousand ordinary days gets promoted, which is a decent argument for treating them as though any of them might.

Trying to make every day meaningful is exhausting and mostly fake, so skip that. Just hold off on writing today down as filler. Answer the message, take the small chance, be decent to whoever is in front of you.
