Annoying is when you cannot find something that you need in order to leave the house. It could be your wallet, your keys, a shoe... just something that you can't really leave without.
If you are like me, most of these items have a "special place" where they habitually get put, and on those rare occasions when one gets mislaid, the stress level starts to rise in direct proportion to the urgency of your need to leave and go somewhere. Just want to go to the store? No big deal. Got an appointment or getting late for work? BIG deal. That's when it gets annoying, and I start pacing the house, going from room to room looking for the missing item.
But if you want really annoying, you need a German Shepherd like Lagniappe to follow you around as you pace from room to room. Everywhere you go, you hear the click-click-click of his paws on the hardwood behind you, and every time you spin around to go look someplace else, you trip over him because he's right behind you!
And he'll skitter off if you yell at him, but in thirty seconds or so, he's going to be right on your heels again, waiting for the moment when you will once again turn and trip over him and practicing his "I'm surprised" look. We've been doing this comedy act for years and it never seems to get old with this dog.
"Fine. Be that way. See if I tell you where your phone is."
