Q: Last year, when I threw a party for my girlfriends birthday, I prepared a nice party with family and friends both excited. My first task was finding a day that would work and trying to be discrete about it. This was difficult because we are both busy and also because I had to alert both of our friends to invite while making sure that none of them gave away the secret. I also had to figure out how I was going to get my girlfriend to the party without telling her that we were having a party for her. After establishing all of these details, I planned the party and sent invites, planned the food, and planned some gifts. This experience was good, but was somewhat difficult . As a the party went on, my girlfriend enjoyed it and appreciated my effort. It was fun and I thoroughly enjoyed the experience.
Question: Who sent the invitations?
A:
boyfriend
