Translation of changeable in German

I am a computer scientist and I also have a small restaurant with my younger sister (she is also already 53). You can come and visit, I will buy you a drink and we could chat a little.
Right now the weather in Italy is very good. We have 25 degrees and the sun is not too hot. I'm going to swim with my brother, the sea is not far away. Wish you also a happy holiday.
