Some days there they are. Bright and beautiful and RIGHT in your face. You have
Encountered The Bee In Your Bonnet Person
These are the just "naturally" crabby people. The Lucy character in Peanuts. The Maxine lady of cartoon fame. They can find you nearly anywhere. In a comment in your blog post. In a reply to a comment on their blog post. In the passenger seat as you drive this buyer around. An Associate REALTOR on the other end of the phone. An email communication from someone that takes you by surprise with THIS part of their personality showing. We all have our off days, but the "bee in your bonnet person" is having an especially grouchy moment. One thing I know is THEY are right and you are wrong, at least for this moment. Don't even try to reason with them.
I think some of it has to do with having a bad day or getting up on the wrong side of the bed or something, but you just have to step back from this massive crabby negativity bent on ruining your day with the venom they spew. I cut people some slack in this area on an "occasion" but if they are the persistent bee in your bonnet person I cut them loose. I have concluded very clearly it is THEM not me with the problem.
Life is too short to hang closely with these what only can be called bitter people.
