I always told my FI that I never wanted to be engaged on a holiday either. He doesn't listen ;-) Case and point, we were engaged on Christmas Day 2013.
Michael and I had been living together for about 4 months (dating for 6 yrs) so I was all excited for Christmas since it was the first Christmas in our new house so I went overboard on decorations, the tree, and his presents. On Christmas morning when it was time to unwrap he unwrapped all of his presents and I didn't have one from him.... not that I need anything for Christmas, but still he didn't get me anything for Christmas, no card, no explanation. I was furious. We had plans to visit my family for lunch and his family for dinner so we were off and running to get ready...(and me not talking to him). We got to my parents and he did what he always does, goes to the shop to hang out with the guys while they cook. I went inside and my mom could tell I was upset, well my dad didn't get her anything either, so we were in a great mood for Christmas, ha. We got through my side's christmas and gifts and said our good byes and headed to his parents for dinner. The first thing his mom does was ask what I got for Christmas...and I just smiled and said ask Michael. She of course laid into him and we laughed about it. We get through their presents and food and we were both exhausted so we head for home. I had just laid down on the couch and was ready to watch a christmas movie when he asked if I had a good Christmas. I replied with a yeah it was ok, how was yours...and he said well I can make yours better and he gave me a christmas box, so I opened it and there were tons of M&M's in it. I just laughed and started eating them when he said to look at them, well each M&M said "Michael and Caitlin" "I love you" and "Will you marry me" I screamed and literally said What the helll..... he brings over my Christmas stocking and my ring was in there.....Yes, in there the entire day and I didn't check it, so of course I had to call everyone and tell them, which they all ready knew since he asked my dad before..... so I felt like a big jerk for acting like a spoiled brat only to find out he did have something for me, the best gift I ever could have gotten!
