We've got a 7 yr old foster son (he'll be 8 next month) currently who is generally a very easy kid to have. Most boys we've had before have been very high energy. This one seems to keep his energy tightly leashed most of the time. However, when our former foster son "Music Man" was here for a while, "Spaceman Spiff" (as I call him online), let loose for the first time.
It's so much fun to see him come out of his shell and really relax into our family's crazy life. I call him Spaceman Spiff, or Spiff for short, because he has such a great imagination and talks a mile a minute when he's excited about something. If you're familiar with my favorite comic strip than you know where the name comes from.
