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
