My mum made me aware of something weird I do when I'm shopping. And I mean every type of shopping, be it clothes, food or furniture.
As an impulsive person, I tend to be very thrilled about buying this and that. I might see a type of food or drink I have been craving for a while (esp. now I'm back in Germany for a bit) and throw it in my shopping basket. Or a new curtain I might be able to use for *something* in the future. Or this nice skirt that I could add to my skirt collection, or ... you get the general idea.
And then, as I continue to stroll through the shop or make my way to the cashier, I might be putting items back. The food item I had been craving for years, leave it behind; the skirt I couldn't live without, I can live without... and so on.
Or ordering a new violin, twice, and then changing your mind. I don't know why I do it, but I do it all the time.
