Translation of frívolo in Spanish-English

Dear Maximilian, I look forward to your visit in Switzerland. After a somewhat difficult start, it seems that we have increased the website traffic and we are starting to receive more visitors.
It is good if you have previously practiced only Spanish, which also shows that you are very good at other languages, and still can learn many things. I hope I'll learn it soon and practice.
I'm fine. I hope you are too. Art is very important for people and everything would be much more boring without art. Nevertheless, there are not many people who appreciate it. I have no sympathy for that.
