Before my son quit his job, he always called home on his way from work in the evening. Normally we could hear the background traffic noise. As he was busy at work and also back in his apartment, he used the time on the way back to call home.
Now he is working from home. He calls back when he takes a break from his work. I can hear from his voice that he is tired, having worked for a long stretch of time.
On 11/4/2012, Sunday afternoon, he called home during one of his work breaks. After the call, I told my daughter, “Your brother always remembers to call back whenever he has a second. I hope you will be like your brother when you are away for college.” She nodded her agreement.
