Three's a Crowd

"I don't know whether or not to keep the NPower bills from last year" Mike mused in Gill's room last night
"I should" I said "Just incase"
"Do you keep your receipts too?" Gilly enquired
"yes"
"Why?"
"I don't know, incase something goes wrong"
"You two" she said indicating to her mike and myself "would be perfect as a couple, if that's not too weird"
"That is a little weird" I said backing away.

Moments later upstairs in my room with my mike

"Gilly says me and her mike would be perfect together because we both keep receipts, I'm scared"
"I keep receipts!" Mike said
"Then we'd be a perfect threesome."
