This happens to me frequently in ICU. A patient and their family will come into the unit, sometimes bearing candy or cookies (yum!), and they come up to me and say, "Hi Sunny, I'm going home today and I wanted to thank you for your care".
I'm like . . . you're very welcome . . . . uh . . . . . who are you??? They're dressed in street clothes, clean-shaven, hair nicely combed . . . I've got no idea who they are!!! But, then, before he can respond, a colleague will run up to him and say, "Hi Mr. So-and-so".
I think I need to start taking Aricept!! Early Alzheimer's!!!
