The company of children. Whether they are running around screaming, making a mess of their pancakes or pizza, or snuggling on the sofa with a book or a video.
Since my wife and I are nearing 50 without having been so blessed (and adoption being prohibitively expensive), it is our joy to note when our friends and relatives have grown tired of their children, and "give them a break" for a while. An afternoon. A weekend. A week.
If you came to our house you could assume we have two, a boy and a girl. Not so...but we have made our spare bedrooms such as would be comfortable for them, filled with our own childhood books and toys.
And I dare anyone to call us "wierd".
