<human>: Give me the gist of the text in a nutshell

As the title says I need some help convincing my parents that travel isn't dangerous. I'll be traveling around Europe for 2 months beginning in June along with my brother (he'll only be going for a month). He'll be 20 and I'll be 18 by the time we arrive. We have family in cities over there (London, Barcelona, Milan) and friends (Amsterdam and Stockholm). I've tried telling them that if anything were to happen we would family and friends to fall back on. To no one's surprise they don't listen. I've extensively looked into the cities I'll be staying in and have only seen others talk about pickpocket and scams. No big deal, I'll be aware of my surroundings and have others with me. It's gotten to the point where I'm looking up statistics to show to them but still nothing works.
<bot>: help with some kind of witty thought out explanation to get my parents to chill out about me traveling "solo" for a month.
