My sister (who lives several continents away) sent me a huge LEGO pirate ship . The set number 31367 31387 for those interested. I spent the evening building with the help of my 13 year old. I also took two or three drams.
I have no regrets.
Edit2: thanks for the birthday wishes. :-)
Will you keep it built or take it apart and built it again another day or take it apart and use the pieces to build something else? When my kids were young they built them and then took them apart and built other things. Now no one seems to do that.
