As I was just commenting to the squirrels at lunchtime, I always talk to any animal I see while I’m on a walk.
Talking to animals is fine, it’s only a problem if you’re holding a conversation. So I say a cheery good morning to the squirrels and rabbits I usually see walking from the car park, but I don’t ask them how their weekend was. That’d be mad.
(for clarity, I don’t call them Mr Squirrel either, just “mornin’, squirrel” is perfectly good manners when talking to rodents. They are non-heirarchical and dislike formality, as a rule, considering it effete)
