history: Last year when I turned 40, I was trying to keep things very low key because I wasn't feeling great about getting older. My kids planned a party for me that I didn't know about and invited all my friends and family. It really was just what I needed to cheer me up.
current: When I turned 40 last year, my kids planned a birthday party for me that I had no idea about.
next: oh wow! that sounds very special!!!
