Unfortunately, It Happen a Lot
I don't know why it happens. I think I'm a pretty interesting person, with worthwhile things to say. I can be in a group of people in a discussion & my comments will pretty much go unacknowledged. I'll be lucky if anyone even looks at me when I say it. Then, it's like a look that says... did you just say something & why? That's usually when I give up & leave or start doing something else...then I get asked...why don't you come & join us, you look lonesome. (No, actually, not lonesome, just alone).
