I think Scuba's suffering from that. Maybe it's coz his mummy keeps disappearing. Last night, we were at Sin Ming for dinner, and we were all leashed along the ledge on the wooden fencing. Scuba kept looking down the ledge. Aunty G said that he looks as if he wants to commit suicide, because it's a distance to the ground below, and his leash is short. Plus he is not as tall as me so his feet won't be able to touch the ground.
He was standing there looking for so long that I started to get worried. I've never heard of dogs commiting suicide. Aunty V, come home soon. I'll help you make sure Scuba doesn't jump off tall buildings in the meantime.
