If you can’t say anything nice, don’t say anything at all.  I am trying to put this into practice, because as of the last two days I have had a problem with sassy, sarcastic, and unnecessary mean comments popping into my brain and sometimes even escaping my lips.  Yikes.  Like when people don’t read the lab book and then ask inane questions, or comment on the wetness and chilliness of a creek.  It is bad.  All of it.  So, I am trying to replace my impatient, mean thoughts with more understanding and kind ones, and only saying nice things.  It’s better for the soul, don’t you think?
