If someone is being nice to you but really rude to your server/goofy to your roommate/mean to their kid, they are rude, goofy, and mean.

I was once dating this girl I'd known my entire life. We were out at a restaurant which she chose, and she was really nice to the server. She ordered something, and then when the server brought it out she realized she wanted to order something else. So the server takes the dish back, and is walking away with it, and my girlfriend says, "No, I changed my mind, I want chicken." So the server brings her the chicken, and when he does she says, "This isn't what I ordered." So he's confused, and he's like, "Sorry, I thought you said you wanted chicken." And she goes, "I did, I just wanted you to write it down so you wouldn't mess it up." And then she goes on about how stupid the server is, and how she shouldn't have come to the restaurant because now the server knows her, and she used to work here. <br><br>I press her for details and she goes on about how the server used to work there, and they used to go to school together, and they had a thing and it didn't work out, and now they don't get along. But then throughout the rest of the meal she's super nice to him. And I'm like, "You were just talking shit about him, and now you're flirting with him?" And she says, "Yeah, I know him, and I just want to get out of here, but I'm also going to request that he not be our server when we come back." So she gets her food, and then we're done with the meal, and she asks to speak with the manager, and I'm thinking she's going to complain about him. But instead she's like, "Yeah, our server did a great job, and the food was fantastic, but I'm going to ask that you not have him serve us next time." And the manager's like, "Okay." And then we leave, and as soon as we get in my car, she's like, "God, that guy is such an idiot, and the food here is shitty." And I'm like, "Really? You just said it was good, and you were flirting with your server, and you said he did a good job." And she's like, "I was just saying all that shit so I could get out of there without making a scene." <br><br>So that was a turning point for me with her, and I felt like I was seeing a side of her I hadn't seen, and it made me think that any time someone is being nice to you, but is being rude to someone else, they are probably rude to a lot of people, and you're just seeing their "nice" side. So if someone is being nice to you but rude to someone else, they are probably rude. If they are being mean to their child, they are probably mean. If they are acting goofy to your roommate, they are probably goofy. It's just a realization that I had about people, and it influences how I choose to associate with people, because I think it's an important thing to consider.
