Getting some quiet time...

Some times when Douglas goes for his walk in the morning one or other of the dogs stays behind.  On the weekend Bruno wanted to stay in bed so Panda went on his own.  One of the side effects of this is that everybody walks a whole lot faster!  Are there things that you like doing on your own without help or company?  What sort of activities can you do if you need to get a bit of a break from everybody else while we are all spending a lot of time together at home?
