hmmmm.....
Let her know about a great feature on her cell phone called "alarm clock" that will wake her up whatever time she sets, thus allowing her to keep her appointments.
I'm finding various different dates for when the alarm clock was invented, but ALL of them were before any of us were born.
(Too bad! because otherwise we could resurrect the "knocker-up service"
"The Knocker-Up (also referred to as a Knocker-Upper) gained prominence during the Industrial Revolution by using a long stick with wire or a knob affixed to the end to rouse customers at a desired time. Clients would agree verbally, in advance, or simply post a preferred time on doors or windows. For a few pence a week, clients could rest assured knowing their Knocker Upper would not leave until he (Knocker Ups were almost always men) was certain a person was awake. Larger Factories and Mills often employed their own Knocker Ups to ensure laborers made it to work on time."
