What is the matter with Christmas lights that can't be turned on after hours of preparation

All the Christmas lights in the living room at my apartment

Some days ago I was trying really hard to make my home more Christmas like. In the morning I went to a shop in Reykjavik and bought some indoor Christmas lights on a sale with a 30% discount. I thought the discount was because there were only few days to Christmas and most people put those lights up in beginning of December. I just thought it was a bargain but I didn't know it was just some junk lights not working at all!

I put plastic suckers to the window and fixed the lights with them. Before I started I tried the light series and yes it was working just great. All colors of lights. Then after one hour work I could just finish half of the lights since I didn't have enough suckers for fixing them to the window. Before I went to the shop again I wanted to see how marvelous the lights would be so I turned them on and... nothing happened. Nothing at all did happen. I just had some ugly dark bulbs made of glass and plastic in my window. Not Christmas like at all.

I was not sure if I wanted to go to the shop just crazy and claim for new lights or if I should just throw this garbage out of the window and just use old fashioned candle lights not depending on Electric at all. But before I could do either of this I had to take down those stupid lights as I did. And of course... when I was in a bad mood scraping down the last lights the whole series turned on. I'm not sure if I was more disappointed or surprised. Since the suckers were more or less still on the window I just threw all the lights up again and afterwards I bought some more suckers. I also found from last year the very beautiful lights made of full wool from my sister and with some candle lights and the christmas houses I also have I just think it is not so bad at all.
