Being glib.
"Given to or characterised by fluency of speech or writing that often suggests insincerity, superficiality, or a lack of concern." 

Dunno or not but I guess sometime I come off as being 'glib' with friends. Not because I am flippant or don't give a shit about them. Sometimes I just can't be bothered with correct words and don't have the quickest of wits. There's usually no question of people who I dislike or would rather never know existed.
Sometimes I am truly snarky with people who pump up their thoughts and abilities because they spend so much time of what they have done and I just can't give a toss. When writing a couple manuals for new employees, one of the first things was "write it for a 5th grader" because it took less time for people to grock the information than having to re-read it. I've found that people who really know their stuff don't show off and can answer questions, in that 5th grade manner. It's amazing.  

The people? The people. I'm so grateful that the numbers I have are so low they are meh. Those very few are mainly people I talk too anyway, so banter or any glibness is fair game. 

Be yourself as much as possible. You don't need to send names or numbers or photos for people to pay attention. Dick or tit pics are not wise, nor are any pics unless you've got bullet proof skin and expect people to comment. Trying to get everyone to be nice is a fool's game with the only winner is anyone who snickers.
