Sometimes I go to bed and think I'm excited to get up tomorrow morning to have coffee.

I could have written this. On a typical WFH day, I have 3 cups of black coffee in the morning, a Colombe triple shot latte in the afternoon, and a double espresso after dinner. My Gen Z kids are in their 20s and don't like coffee quite as much (or share my complete caffeine immunity).

DD has a drip coffee maker for am coffee and likes local coffee shops in her city. DS has a Keurig machine and will always get a cold brew if someone else is buying.

No. My kids like sparkling water, particularly Vichy.
