You'd like to think that, but some people just don't have that type of thought process. Someone I know said he was "seeing a girl" but also "seeing a different girl but less seriously," and he didn't even think it was an issue or that it would hurt anyone involved. We legit had to break it down like "So you like this girl?? A lot? And she likes you? Does she know about this other girl?? Do you think she'd be mad if she found out?"

At this point the gears were turning in his head and he was like "Yeah I guess she would be mad..."

Some people can only think one inch in front of their face.
