I was a child not long ago (I'm only 23), but I used to run around all the time, just like you guys! We (tried) to build treehouses in our backyard and ran from one friends house to another. And while we had to ask if we could go to the park, we could usually go, that is, after we were like 8 or something. But then the whole Polly Klaus thing happened (she was abducted from her bedroom window) and it scared a lot of people. There was a whole fear of even being in your own home. Anyways, that made a lot of parents keep a much tighter reign on their kids. And like Barb said, be available to supervise. Which is hard for most families now, who have to have 2 incomes to keep their families running. So it's just a tough world to live in. And we have to make a lot of effort to go to the gym. Thankfully I have a really fast metabolism right now, but I know that once it slows down I am going to need to go on more walks and work out more often.
And yes, it is convenient to grab fast food. American needs to slow down. We all do so much, run our kids from activity to activity. And just never stop and smell the roses. Tonight I have nothing to do, and it's wonderful! I love time to just relax and go slow!
Anyways, enough or my rant!
