One picture shows Norah and Avril sitting on my aerobics step. Another shows Norah before Avril was even thought of.
Now and then I like to compare my pictures, to see how quickly my kids have grown. This serves to remind me how quickly time flies, how what seem like insignificant minutes add up to hours, days, years.
For what is your life? It is a vapor, that appears for a little while, and then vanishes away.
