About 1992 we hired a young single male teacher. Tom was well qualified and quickly became a very good teacher.
Tom was single and as single guys go he could have good time.
Soon Tom was married to his long time girlfriend and of course children appeared. Now Tom is a very affectionate, caring and sentimental guy. Tom's wife is a very lucky woman and his kids have experienced a solid family upbringing. The family traveled and participated in sports.
I saw Tom and his family from time to time and it was always interesting to see the kids grow. Tom was very proud of his two boys. Oh yes, they learned how to fish! They also became good hockey players.
Tom is a Face Book friend. The other day he said, "It's happened and I can't believe it. We took Gord to the high school orientation night!" Tom couldn't believe that his son had grown up so quickly and was ready to enter high school. Yes, Tom was freaking about his age.
So we have kids and are extremely busy with them and don't notice the time going by. I was surprised when my kids were ready to start school. It seemed like the time they were little went by very quickly. Where time really seemed to race is when they were in Middle school. Once they were through Middle School they seemed to be out on their own much more and away from home. I still wanted to have them at home.
All at once a certain milestone is reached and we are keenly aware of time going by rather quickly. Our kids are growing up and we are getting older.
I'm sure the people who have children mark the passage of time by what happens with their kids.
