The watch command doesn't accept ordinals (1st, 2nd, etc) and this causes problems when you have an item in your inventory that has the same name as a person in the room. Address works fine, but sometimes people forget to address you in crowded rooms and when that happens, if you have something on you that has the same name as them, you simply can't watch them. So if there's a guy named Gray and you have some gray jeans on you, it's an issue.
It would be lovely if this could be changed.
