One thing that makes me notice the passage of time is music. Songs have the ability to take me back to the time when I first heard them or special events when they were played. For our trip last weekend I made up a CD of songs that we associated with previous holidays or concerts. It was great to listen to on the journey & reminisce. We couldn't believe it will be 20 years this summer since we went to Belgium together!
Unfortunately Olivia's image won't open and she is away so I can't ask her to resend it.
