+[description]
+
+Here's a trick so that you can sleep a bit longer: just do all your morning activities in parallel universes, and then at the end, merge them together!
+
+Here, you see three parallel timelines - can you build a situation where you consumed a baguette, a coffee, *and* a donut?
+
+The "merge" card will help you - try it!

+
+I wonder if you're more relaxed when you *sleep* in parallel timelines...
