Everyone follows a different life path, there is no set way to do things – though society and your family like to tell you so.
This isn’t always trying to be mean, some people just don’t know any other way to go about life, and project that onto others.
I reckon most of it is said from a place of love and worry, so maybe when it is said, just remind them that you’re getting there and that even though they might think it needs to be a certain way, they need to let you find your own.
Good luck with the move, I hope you find some good people to connect with on your travels – I’m sure you will. Travel is built for people like you, we’re not all meant to live our lives in the same place and I’m sure you’ll meet some amazing people to share your experiences with. 🙂
