Early in our marriage, OH and I agreed that, on weekends, the first one awake should get up and make tea. This resulted in the two of us lying doggedly in bed, pretending to be asleep, until whatever hour someone's bladder finally forced them into a vertical position. OH finally overcame the problem with a Teasmaid - a brilliant device which we've been using ever since (well, I think the current one is the fourth one in 45 years).
Every night, we fill the tank with water, plop a teabag in the pot, put mugs, spoon and a small flask of milk to one side and wake to the glorious fragrance of freshly brewed tea.
If you don't want to set it for a specific time, just wait until you wake naturally, lean out of bed and press the Tea Now button.
I truly believe, if we ever divorce, the ferocious custody battle will be about the Teasmaid!
