Disclaimer: I own nothing but the plot.
Whilst the blanking tactic had been fun, it had one significant drawback: Moim and Petebog could always just ignore the ignoring, and since Cathy and I were pretending Petebog didn't exist, we couldn't draw attention to the fact that we were ignoring him. So we had to change our plan.
"I say we declare war." Cathy announced.
"Isn't that what we were doing anyway?" I asked, confused.
"Nope. That was just nonverbal arguing. Things may well get messy now."
"What's the plan?" I smiled. Messy is fun.
"Do you want some coffee?" I asked Pete, smiling innocently.
" That would be lovely, Beck." Both he and Mom had been visibly relieved to see that our campaign had, apparently, come to an end. Enjoy it while it lasts... I walked into the kitchen, trying to look like there was nothing underhand taking place. I made the drink, but with two barely-noticeable changes to the recipe.
"Here you go!" He took a sip...and promptly spat it out, inadvertantly spilling the liquid into his lap at the same time. Cathy bit her lip, trying not to laugh. That was the best spit-take either of us had ever seen.
"Are you alright?" I hoped I sounded suitably concerned.
"What the hell is this?
"Coffee."
"What's in it?" I opened my mouth to respond, but Mom shot me the 'don't' look.
"What did you do to the coffee, Beck?" She asked when our victim was gone.
"Nothing! All I put in it was coffee beans, milk, water and sugar."
"Did you use the milk bottle at the back of the refrigerator?"
"Yeah, why?" I tried to look puzzled.
"Oh, Beck. That bottle was off! I thought I told you!" She had. I just chose to forget.
"I forgot. Oops." I paused in mock-consideration. "And I think I might have got the sugar and salt mixed up. My bad." At this point, Cathy started laughing.
"Did you two plan this?"
"Nope." we chorused.
"You did, didn't you?"
"We were just trying to help." I said, defensively. Cathy was still giggling helplessly.
"How is sabotaging a relationship helpful?"
"We don't like him."
"He treats me like I'm a little girl and he hates Beck." Cathy added.
"And he knows too much!"
"I'll talk to him about all that. Just...promise me you'll stop spiking his coffee." The two of us agreed.
After all, we weren't going to repeat ourselves, were we?
