It’s really simple: Just because I’m not in a relationship with a woman doesn’t mean I can’t do things as though I am in a relationship with her. Isn’t that what we do every time we have sex? Of course it is. So if we can have sex even though we’re not in a formal relationship, what’s wrong with walking her dog?
The only reason I would say no is because I wouldn’t want her to get the wrong idea. I am not quite ready for a relationship, and she knows that. If I walk her dog for her while she works overtime, the gray area we exist can possibly get even more foggy. But, that’s not a really good reason to say no. Or rather, it’s not a better reason than the one I have for saying yes.
This girl and I may not be together, but we are definitely involved with one another, and I shouldn’t need a title to be a nice guy to her. Saying no to walking the dog would only be to save face, and my face is just fine. For this girl who I am not in a relationship with, I am going to walk her dog because I like her, and more importantly she likes me, which means she would do the same thing.
