Sick Pet Revisited

Monika's Crohns flared up so she had to go to the Emergency room last night.  She and Bob left at around their normal bed time and did not come back until way late. (1:30)  Then Bob laid and tried to sleep so he would be awake for work tomorrow, but he could not fall asleep.  He says he is running on auto-pilot because he did not get enough sleep.
