I'm inviting you to a fun game of Secret Santa. Secret Santa is a fun game in which everyone buys gifts for one other person, who doesn't know who bought their gift.

The person you have to buy a gift for is {}. The budget for this year is 15€.

We will be exchanging gifts at our Christmas Party, on December 1st.

See ya there!
Secret Santa's helper Malicious Carly
