Your 19 you don't have to do what your parents want you to do, you are legally an adult so just go, and tell your parents that you have gone.
You are 19, you don't need their permission. Just do what you want. Yes though you can set up call forwarding to a cell phone, and no one will be the wiser.
Others have said that since you are 19 you are legally an adult and can do what you like...well not quite. If you live with your parents and are financially dependent on them, you are still under their authority. When you are totally independent from them in every way...completely paying your own way and solving your own problems, then you are an adult.
Who is going to pay for this travel? If you are still dependent on them, you need to come to an agreement with them, or wait.
Yes, it is possible that your parents call your U.S. tel. Number and they don't really know where you are. Keep in mind that YOU have to pay for the roaming charges, and they are awfully expensive.
On the other hand, why do you think your parents don't wanna let you go alone? Well, because they love you and are concerned that something bad might happen, and this is very normal for any parent. Why don't you try to find somebody that will travel with you, and your parents might be ok with that.It is not really a good idea to trick your person.
Think about it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
