Pick a time

any time.

Eager to cook the folks a Sunday meal before the term fills up with weekend rehearsals, I invited any of them who were free round today.

Since my parents were going out for a walk, I checked with my Mum what time she'd like to eat.

6 o'clock? ( Like some random, notional tea-time.)

She laughed because we always eat at 6 o'clock.

You can have breakfast any time.  But lunch is at 1 and tea is at 6.

And now I must attend to the veg.
