I like that if we sleep in a bit, I don't feel guilty about it. We can just chalk it up to a busy week and often a late Sunday night.
I like that my house is usually sparkling clean. We host a small group from church here each week (changing to every other week though) on Sunday evenings. So I always make sure the house is tidy, the toilet is scrubbed, and the floors are vacuumed before everyone comes. And it doesn't hurt that when I get up Monday morning my house is nice and clean.
I like a fresh start with a new week. What will this week hold? You never know on Monday how the week will end.
Is there anything that you like about Mondays?
