One night, I called my 27-year-old son, he was on his way to a company. He says he would call me back shortly. Strange he did not. This was pretty unusual. The following morning, I called but got no respond, which worried me. Later, he texted me from his iPad, tells me he lost his phone right after my first call. He was very upset because of it held many memorable photo and texts. He said that a co-worker called phone, and a cabdriver answered. The driver said he would gladly return the phone or gave his cell number to the co-worker. What lucky my son was!
