['When I turned 30 years old, my wife shocked me with a surprise birthday party!', 'That sounds like a lot of fun! Did you have a great time?', 'I sure did.  She had contacted my older siblings who lived out of town, my parents, and my friends.  She put all kinds of work into it.  I was just thilled!']
That was very thoughtful, you are very lucky!
I remember when I turned 30 years old that my wife had planned a surprise birthday party for me.  I remember that she had gone ahead to a restaurant to meet me since I was at work.  I headed there right after work to a private room (unbeknownst to me).  Everyone yelled Surprise, and I was taken back!  I couldn't believe it.  What a great day!
