Empty Nest-ish

Chad has been gone for about a week.There isn't cell phone service there,but he does have wi-fi. So everyday I check my email,hoping to hear from him. Several times a day. Like maybe he had time while he ate breakfast. Or lunch. Or dinner. Or before he went to bed. I guess he's just working really hard and doesn't have any time. He wouldn't ignore his mother,right? (In all fairness, he called 2 days ago from a phone booth. I'm just anxious for him.)
