But - don't panic if they haven't shown up yet!
for me it's the time 11:11 or 1:11 Every since my Mom died back in 1979 (I was 17), I've found myself glancing at the clock multiple times a week and frequently the time will be either 11:11 or 1:11. It happens too often to be a coincidence. I know it's my Mom checking in and sending a greeting. Different clocks at different places and I don't think about it ahead of time (ie.. it's getting close to that time so let me look at the clock). I love that connection.
