Missed Call

So after coming down with a sudden cold, I took a long nap during the day. During this nap my phone rang. Mom Cell appeared on the caller ID. Half asleep I decided I couldn't deal with anything right then so I would listen to the voicemail.....No voicemail. Now all I can do is wonder what she could have possibly wanted to talk about. Just say hi and I love you? Or try to explain things she probably doesn't know I know about?
