Are you alone?
Are you busy now?
Are you married?
Are you sure?
Are you with someone?
Be careful.
Bye, see you tomorrow.
Calm down.
Can I ask you a personal question?
Can I give you a piece of advice?
Can I have the bill, please?
Can I have your telephone number?
Can I talk to you now?
Can I tell you what I think?
Can we talk?
Cheer up.
Coke, please.
Come in.
Congratulations on joining the company.
Congratulations on leaving the hospital.
