Can you tell the difference between these 2 phones?Neither can I.
One is mine and the other is Brian's.
When Brian was here on Tuesday, he took his phone home with him, and he took my phone home with him. For 3 days he was my social secretary, passing on all of those voicemails and work texts. I had to set the alarm on my clock radio, of all things, to wake up.
I called him twice a day to check in.
He's glad I have my phone back.
But not as glad as I am.
