I think you're right! One of the first things my Mom gave me after my Dad passed was his guitar pick and I've kept that in my wallet for two years. A few weeks ago she gave me the guitar strap and that was the catalyst that pushed me to buy the guitar. I think Dad wanted me to start playing again.
What a wonderful gift for you to find those tapes with your Dad's voice on them. I have a few videos with my Dad speaking but that's all we have. Thanks for taking the time to drop by my blog! Take care of yourself and enjoy your week!
