Yep, a calendar is a neat reminder of what you have done throughout the year. I use mine to make note of things that need to be done on certain days and also for what I've done on that day...never anything of length...might say, went to lunch with Mom or spent day at home or Hubby and I went to Ithaca...whatever!
And Bobert, not that it's any of my business, but I thought the two of you were retired...so for the life of me, I can't figure out how it is you are unable to set aside a day for one another (if that doesn't work for you or you don't like the idea, that's ok...just wondering how you don't have the time). Also, has your wife made any new friends in the area that share the same likes? She might enjoy a day out with them!
Personally, I'm not into guitars (tried that, not coordinated enough) and I am easily bored at guitar shops but I do go with my husband and humor him just as he humors me at the violin shoppe. I suppose marriage is like that though...give and take. One summer I went to a Metallica concert of his chosing and he went to the Lilith Fair with me...LOL...if that isn't give and take, I don't know what is!!! *G*
