If I can’t come to my friend's party,
...
If it snows tomorrow,
...
If I want to leave,
...
If Dmitriy gets sick,
...
If you get hungry,
...
If I fail my exam,
...
If I don’t answer the phone,
...
If I get lost,
...
If the party is canceled,
...
If my friend borrows my shoes,
...
If I arrive late to school,
...
If the shopping mall is closed,
...
