My mother is aged. She is easy to complain now. My problem is that I am busy with my work recently and hardly spare my time to listen to her. When she telephoned me, I was at meeting, on driving or having class. When I telephoned her, it will be too late for her to answer. Days by days, a sense of guilty attacked me. Then what should I do to get a chance to listen to her complaint? I equipped her house a CCTV camera so that I can see if she is sleeping when I plan to make a call to her. I phoned her while I was having lunch with a earphone on my head so that I can hear her murmur clearly and tried to nod to her through video camera to comfort her. I phoned her while my husband drove home after work, which made her thought I changed my job to a night shift because I finished my work late recently. She got eased because of our regular chat through visual telephone and I relived myself from the sense of guilty.
