GAINING ATTENTION

HALOOOOO! ATTENTION, PLEASE! CAN YOU HEAR ME?
It's difficult to get someone's attention if we don't know how to do it. You have to shout out laud so they can hear us.

- Excuse me, ....
- May I have your attention, please?
- sorry to trouble you.

The informal way:
- Hey!
- Listen to me please!
