Yesterday while cooking I set off the smoke detector, no I did not burn anything. They go off when I cook over a high heat. And yesterday once they started going off they would not stop. I ended up having to disconnect them all (they are hard wired with an interconnect) and I replaced them this morning. Aaaaaaaand let me tell you, I had a sleepless night last night knowing there were no detectors installed.

Differentiating between European countries is hardly as important as piling onto the “Europe shits on America” bandwagon that this entire site has rapidly become. Literally any issue will turn into Europeans talking down to America. Nuances between EU countries? Who cares!
