Hi,

this is my first post ever on Reddit so sorry if I do something wrong.

I'm 17 years old and I'm a little embarassed asking this since I feel like it's a basic thing that everyone should know how to do. But, anyway.

Tomorrow I need to leave my house by myself because my parents need to do some stuff and they aren't at home.  


What should I do? What do I have to check?   
I'm so scared of doing something wrong and mess things up.  


Also, I have to take a taxi by myself to go to another part of the city and I'm scared. What are some tips?
