I'm still getting used to all the buttons and programs, but it's definitely an upgrade from my old "dumb" phone. It has been a great new way for me to video chat with your uncles and aunties back home! Of course, your brother already seems to be completely comfortable using the new phone for his games and music. He didn't actually say "thank you," but I'm sure he's grateful... How much should I pay you for August's phone bill? I used to pay $70 a month total for our old phones.

It's just been really busy at the clinic getting my accounts set up. I just found that since we're part of the National Clinics Association, I'm eligible for a pretty big discount on my cell phone plan. I don't have to change numbers or anything: the carrier will just apply the discount to the existing plan with my phone lines. I know you've been thinking about getting new phones for you and Manu. I could add your two lines to my account and bump up the talk time allowance from 500 minutes to 700 minutes, and the data allowance from 4 GB to 6 GB. What do you think? Give me a call if you want me to set it up. -Zayna
