Episode one is called "Getting Up."
The verb to get, "get," up means to get out of your bed - to leave your bed.
So, after you stop sleeping - after you wake up, then you get up - you get out of your bed.
Lucy begins her story by saying that "On a weekday," that is Monday, Tuesday, Wednesday, Thursday, and Friday - those are the weekdays (all one word), weekday.
The other part of the week is called the weekend, Saturday and Sunday.
"On a weekday," what some people might also call a work day - a day they have to work, Lucy says she "usually gets up around 6:30" in the morning, but she sets her "alarm to go off at 6:20."
Her alarm, "alarm," is what makes noise - what wakes her up, usually it is an alarm clock that you can set the time to.
To set your alarm, "set," means to put it to the correct time.
