Shopping list vs What I bought

Things that followed me home from the shops today:

1 roll velcro tape
1 jar cocktail onions
1 piece of nice looking shark
1 baguette
1 block lurpak butter
1 lb teeny tiny rosy waxy potatoes
1 lb asparagus
6 large perfect white mushrooms
1 block popular brand mexican chocolate
36 count white corn tortillas
salsa ingredients (ripe romas, jalapenos, cilantro, onion)


So what?

Well, not one of those things were on my shopping list.

Why is it that I got to the shop and get distracted from the things we need (i.e. toilet paper), with all these things that I can only explain by telling D that it seemed like something I had to have.
