As you trot to your front door from your car,you take out your house key, per routine, ready to unlock the front door and return to the embrace of your house, when it occurred to you that, if you have trouble entering and exiting your car, the stairs, narrow corridors, and awkwardly placed furniture in your house won't help.
Just then, you took a look at the lawn you've just mowed this morning, and had other ideas. All those could be dealt with later; you simply want to immerse yourself into the instinctual thrill of running again, and what better place to do this than the grass field right in front of your eyes?
You step on the grass field and allow your legs to carry yourself around the lawn in circles. This field isn't as vast as the one in the park, and the fence means that there's nothing to catch — hang on, where did the hare you've caught go? Probably dropped it before entering the car. Oh well. Still this does not diminish the ecstasy you feel while sprinting around freely. You could do this all day long. No trees to swerve from, no picnickers to avoid: the entire field belongs to you and you alone, and you feel completely free to run at your own pace and for your own enjoyment, free from the judgment of anyone else. Right?
"Oh, a new dog again? It'd better be a tame one." Followed by a sigh, from your neighbouring old lady that's usually nice but a little disdainful of pets, treating them as nuisances. She sat on her second-floor balcony and gazed at you with an expression of mild dismay, as if you're an untrained pet allowed to roam too free, even if your L-shaped taur body should be a dead giveaway to something deeper going on. Even setting that aside, why you exactly? You've not even made a sound, and racing greyhounds are usually trained against barking anyway. Could you even be a nuisance to her at all, given that your properties are separated by a fence taller than you?
Still, sullen and slightly ashamed, you droop your ears and your tail, slowly approaching the side door to your two-storey house. You've never even once stopped to ask yourself: would your presence be unwelcome to anyone? Now, the answer is crystal clear.
