I play a lot of airsoft. That alone isn't very useful in day-to-day life, except for cardio.
But I own eleven airsoft guns. Mostly pistols.
Airsoft, combined with my love for the Payday games and John Wick movies, is also the only reason why I own any three-piece suits.
My housemates have an odd mix of nicknames for their cats. One of them has a shortened name, two of them tend to get extra syllables added to their names, and the last one, Goku, is just Goku.
I usually can't keep all their names straight, so when one of them bugs me, I tend to just point at it and say "...cat".
