This is our garden shrine. Patrick taught him to bring flowers to Buddha and we taught him to gasho (palms together and bow in respect). He will say "Buddha" (sounds like "B-dah") and also will gasho when we say "Buddha" or when he walks past the shrine.
Interestingly, he's taken a liking to a picture of Robin that we have in the house. Today, he picked it up and said "B-dah, B-dah" over and over again, and then hugged the picture. I then took the picture from him and he made the gasho gesture. Both Drew and I just stood there with our mouths open staring at him in disbelief. Don't know what to make of it really, except to say that it was a precious moment for us, given how important Robin was in our lives.
