I want to keep my spot in line
That's reasonable. Why do you want to keep your spot in line?
I want to be first in line. I don't want to have to start over.
Fair enough, you don't want to leave your spot in line. Especially when you're first.
I agree.
Queues can be very tiring, huh? But the more you show your patience the more it will pay off in the end! Being the first in will give you the greatest experience.
