@jesusdiaz: bummer!

I gave up LEGO except for one racing car that still resides on one of my cupboards.

I still have four huge crates of parts somewhere round here.

@icepick314: That happened to me once in my life.

I was 12 years old and had just bought a huge truck with a trailer and a helicopter.

I realised that a crucial part was missing (one of those custom parts). That thing wasn't a gift, and I spent about 120 Deutsch-Mark on that toy.

So I wrote a letter to Lego Germany, with a picture of the missing part attached.

About two weeks later they sent me that missing part along with a second model and a apology.

I gave that second model to my best friend as a gift.
