It's kind of funny...my husband and I went to a friend's birthday party, last night. We climbed the stairs to her attic rental, and then we both hesitated before he finally reached out and knocked on the door.
"You don't like to knock on doors, do you?" he said, and then then broke into a sheepish grin as he realized what he'd just said.
"Kinda burnt out", I replied, laughing.
And then the door opened, we yelled "Happy Birthday!" to our hostess, and stepped into the warm, inviting apartment.
