The surprise was that I would be getting my first haircut.
How did you feel about getting your haircut?
It was an inconvenience for me, because I didn't want short hair.
If you do not want short hair it is acceptable to keep it long. Nobody should force you to do things against your will.
Well, I think I actually like how it looks now.
It's good that you like your new haircut, just keep in mind for next time that your haircut is your decision. It would suck if you had been made to get a haircut that you didn't like, and you would've resented whoever forced the decision on you.
