I was having a good time in Vegas last weekend but then I got hit by the sunday night blues.
I got an extra hour of sleep this weekend, had quality time with women friends, had a whole unplanned Saturday, enjoyed meaningful worship today, spent sweet time with my mother, got in a delicious Sunday nap, cooked good substantial food with things I had on hand, started a good book…………seems a shame to have to break this golden time up with a return to the office tomorrow!
