Looking for a native English speaker in Munich

Hi there! I am looking for a native English speaker in Munich who can help me train and improve my English! I have been living in the US for two years and I don't want to get rusty in my language skills. We could meet once a week/month for a walk or a coffee and just talk. Of course I would pay for the coffee! While talking you should interrupt me and correct me if I've made a mistake. Not longer than an hour or so. Looking forward to hearing from you! Best wishes!
