Bonus Tips and Points

1. Many grammar books will tell you that the proper way to ask for permission is to use "May I…?". This is true, but these days most people use both "May I…" and "Can I.." when asking for permission. Actually, most people consider "May I…" to be more formal and polite.

• May I go to the bathroom? = Can I go to the bathroom?
• May I see that? = Can I see that?
• May I borrow $5? = Can I borrow $5?

2. It is also possible to ask permission for a third person.
