Find a place to relax, have a good lloooonnnngggg lunch, enjoy a good cuppa tea and.... Read your favourite novel!
Well, not only on Mondays, i spent most of my available weekdays enjoying my afternoon this way. =D
What's best? You know your best girlfriend (Babe, i think we can celebrate our one decade anniversary?!) enjoys doing the same thing too! Awww... Sometimes, you just don't have a speak to make yourself known.
Mondays are never blue... ;p
