"Nerd," she says, which doesn't even make any sense, but luckily cats don't speak English.

Indeed, the utterance doesn't make a lot of sense to the cat -- or wouldn't, if the cat could understand human speech, which of course it can't. So it just continues meticulously cleaning its paw, not responding any differently to anything that April has said. 

"Yeah, I don't know what I meant either."

The cat definitely cannot understand human speech, because it is a cat, and so continues cleaning its paw. 

She finishes putting the rest of the groceries away. "Go on, shoo."

The cat finishes cleaning its paw, unhurried, and then hops up on the counter top near the sink, and turns to look at April. 

"Aww, c'mon."

The cat bats its paws at the faucet, and turns to look at April again. 

"I'm doing this under protest," she says, but she turns on the water.

The cat purrs, then sticks its face sideways into the stream of water to thirstily drink for the next few minutes. 

"I feel the need to remind you of the rule against peeing on my floor," she says, sitting down and getting out her phone.

The cat pays this admonition no heed, and continues drinking. 

Well, naturally.

Eventually, the cat finishes drinking its fill of water, and hops back down off of the counter to rub up against April's shins once more. 

"Now will you get out of my house?"

The cat boops her shin with its nose, and then turns to stalk out of the house. 

"Bye! Go be cute at someone who cares!"

The cat settles into its spot on the loveseat, stretching and relaxing, then curling up for a nap. 

It takes her a minute to get up and close the door because she's busy playing Candy Crush.

So, same time next week?

Same time next week! The cat is still there, on its back, batting at dust motes lit up in the sunlight, but it turns to look at April when the door opens, and jumps down to rub against her legs when the door is closed. 

"Slacker," she says, but she sounds almost affectionate.

The cat boops its cold nose against her shin and goes back to rubbing up against her legs. 

"Flatter me all you like, you're still not getting any bacon."

The cat is just a cat and so has no ability to understand the word bacon, and so has no reason to change its behavior when it hears the word. It just continues rubbing up against April's legs before jumping back up into its patch of sunlight in a loaf to watch her leave. 

She goes, she comes back, she opens the door to let in the cat for the Grocery Inspection.
