One of the biggest impulsive buying I've ever done

Went to a shopping centre out of the town. The last time I went was... well before my hubby passed away, I think. Actually I don't remember much.

I had to go there because what my big one wanted for Christmas was not in the town. But I also bought what my wee one wanted and also found one of my most favourite films' DVDs "The Tricolor Trilogy" by chance. I wasn't going to buy anything for myself today. But I had wanted the DVD badly for some years. So, I lifted the box, thought about it for... 5 seconds and went to the till. And I spent all the money for Christmas treat/present for myself this year in 5
minutes. (I had to queue up at the till.)

Now I'm trying to convince myself that I have been a good girl all year and I deserve the DVDs. Please don't tell me how I have been this year. Surely I deserve the DVDs. Surely...

I like the shopping centre but I should go there only once or twice a year (maybe 3-4 times?). If I go there, I spend my money too much too quickly...
