That's a pretty relevant point because when I've been around her in person she seems to either have a very hard time connecting with the group or seem really out of place trying. I think her social media persona gives her a lot of what most people get in regular life, which wouldn't be so bad if she didn't make it all up.
Oh, yeah, I know what you mean. One of my friends, when he's not at work, spends all of his time on the computer. Day in and day out. He has tons of online friends and is always talking to someone. He's very personable, really well liked. When we go out drinking together, with other friends of mine, we make sure he feels included but he has a real hard time of it. He's just more comfortable online. I wouldn't be surprised if your friend felt similar.
