I might say suck with a colleague, in private. Once I got to know my clients better, depending on who it was, maybe. Not in a team meeting, ever. Not when I was a teacher, either.
I had a few clients who swore incessantly this past year. It wore even me down. The f word becomes meaningless. This is coming from me, who used to be called Tilly toilet mouth. I cleaned up my act when my kids got old enough to understand and then relented a little when they became older.
Good thing that I am not in a field that requires social networking. I do use Facebook, but minimally, and thankfully, medical professionals have privacy rules to adhere to. I don't even like to send an email about a client to another therapist, but some people do. So, no need to share my thoughts with anyone.
I'm known as pretty frank, also, but I guess, in a slightly different way. I don't believe in sugar coating, but different rules for different professions, I suppose.
I could not describe myself in 140 characters, after 30 years of teaching, going back to school, and looking for a job now.
