My work threw me a mini shower a couple of weeks ago. Just some cake and ice cream, and a card with a giftcard in it. Nice, sweet, and simple. Everyone on my team and the team we work closely with signed the card, but I don't know who actually purchased the card/giftcard - if everyone contributed, or just my boss and one or two other people.I thanked them all in person and via email shortly after we all went back to our desks. Do I also need to write a thank you card? I would be more than happy to write one, except I am not sure who exactly to write it to. I don't want to write an individual one for all 12 people, particularly since I don't want to make them feel uncomfortable if they didn't actually even contribute! I wish we had some kind of bulletin board I could hang one on, but we don't.Anyone else have a similar gift? What did you do or do you think I should do?Thanks!
