You have exactly 10 DAYS to figure out what to do for your mother for this special day. Maybe you could start now by writing a most heart-felt card! The best way to make your day spectacular is to try to forget about YOU being the mother and honor YOUR mother (and Grandmother!) What about an old photo of the 2 of you restored and framed...maybe even from your childhood. You may not find it on your computer, but maybe you could dig something up.
Whatever you decide, start working on it!
