Tilla likes to make my wife laugh, too.  He walked out of my room, where he was waiting for me to leave my seat after I finished watching TV.  My wife had just gotten up to use the bathroom and Tilla accommodated her Lazy Boy chair, where she sleeps.  Our dog was standing up right in her chair and his tail was thumping vigorously.  My wife could only laugh as she tried to sit back on her chair and he immediately vacated the seat.  Tilla has a sense of humor.  Don’t tell me animals don’t?  He does.
