The sender is 10 and says his hobby is handball. I don't see a handball team in Neustrelitz so I don't know what team he would support. Neustrelitz is a city first mentioned in 1278, and has a population of about 20 000 people today. It is found in north east Germany.  The city is known for the Immergut Festival. It is an annual music festival that first took place in 2000 and focuses on indie rock. It is one of the largest festivals for indie rock in Germany.
