American and Natural speed please!
when my friends can't answer my call, I will text them to let them know I called and wait for their reply.
I believe when the person I’m calling is in a conference or in a cinema, it's better to text him instead of making a telephone call.
Yes, I remember when I had to refuse some friends requests I had to think carefully for a long time about how to reply.
I send text messages almost on a daily basis. I always text my friends and family to say hello, chat and make travelling plans.
