Hello friend, I am feeling very nervous!
about what may I ask?
well you know we are going on a trip soon but we have to rely on someone else for our transportation, so I am nervous about trusting that person to not leave us hanging.
Is the person someone you know well, a long time friend, a family member?
My brother, but he is not very trustworthy. Guess I am just very nervous about the whole thing
I would talk to your brother and let him know how concerned you are and ask him for reassurance
