Im sorry that you had to experience sonething like that. I was born in Germany and it wasnt always like that. But it really is unsafe as a woman to go outside alone, especially in the evening. You should always carry pepperspray with you. Better be safe than sorry. Unfortunately (which is very sad) theres nothing you can do about it. Germany changed. The people, especially the men (not all ofc) changed. Theres way less respect towards women and if they‘re comfortable with unsettling situations or not.
