This morning there was Mathew poking his head under the patio wall.  
Bruiser was sooooo happy they were running the neighborhood together and
you could see the joy in their posture and movement. Now the rest of the
story I found out later.  I got a knock on my door and it was Paul,
Mathew's person, he told me that this morning Bruiser had paid them a
visit.  He was at their patio door and wanted to see Mathew so they let
him in and they wrestled around for awhile.  Mathew is now neutered so
they let him out to play.  He said they are going to let him out in the
mornings from now on.  He said he hoped Mathew did not bother me.  I told
him the truth I was really really happy to see him because Bruiser was
driving Maya and me crazy.
