Luxembourg transformed me in a meteo dependent person and these long and rainy days don’t help much. So if you need somes good vibes and energy (and don’t count on the sun because it will shine in other countries) why not try a workout. We have been speaking so much about childhood in my French course, so I wanted to remember my child long jump rope sessions. So YouTube helped and now I have again the power to cope with the rain.
Hope it helps you too!
