Goodmorning Grumpypants. Oh, how I adore you!
Should anyone (anyone, including you) suggest to you that this is a bad thing, a bad day lies ahead, flip em the bird. A perfectly reasonable response for a grumpy person.
Bad by definition means inferior, defective, unacceptable, unwelcome.
How about if today you greet that grumpy part with open arms. Embrace the one who is feeling angry, frustrated, doubtful. Maybe you won’t give her a hug, that might make her want to punch you in the face. Still you can be there and meet her and hear what she has to say. Find out what she needs.
And love her like mad.
