It was around the holidays, and the entire base was decorated from head to toe for Christmas, but you didn't celebrate Christmas. You celebrated Hanukkah, so your barrack was decorated accordingly. You didn't think anyone would point it out until Ghost walked in along with Price and Soap. Soap noticed your hanukkiah and pointed it out.

"What's with the candle holder? Is it a culture thing?" Soap asks, gesturing to the hanukkiah as Price scans your barracks, not saying anything.
