Your mother is wrong. Men and women play the guitar. I think your mother just finds it unfeminine.
Tell her if it is not a guitar, then it is symbols or a pipe organ - which would she prefer. Given those choices, I know she will choose the guitar. But she is your mother so she gets the final word.
Realize that you cannot grow your nails very long at all if you are going to play a guitar.
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.
