My friend's office is getting really into Halloween and decorating their cubicles and planning a party for the day of. My friend is on the committee to plan the party and is sending out emails to the office to remind them about the costume contest, etc. One of her coworkers emailed her back and said she did not celebrate and was offended.
How would you reply to this coworker?
ETA: Friend just let me know that coworker told her the reason she didn't celebrate was she thought the holiday was greedy and encouraged people to "dress slutty."
