By the time I arrived there the party was over
By the time you dress up breakfast will be prepared
By the time you come back you can finish it
By the time this mail arrives I might be on a vacation
By the time you graduate school I will be married
By the time I arrived at the ticket office there weren't any tickets
By the time she became 4years old she can speak language very well
By the time I get out of bus the weather was good
By the time I arrived home the rain stopped
By the time the police came criminals already escaped
In case it rains bring an umbrella
In case you are cold I brought a sweater
In case I forget, I wrote your phone number
In case you need help write my email address
In case you wonder why she came, I'll explain
In case you forget passport, be prepared
In case it is wet bring some extra clothes
In case you can't find the place, I will draw a map
In case you can miss I will give the recent information
In case she arrives early go to the airport before
