And yeah, violin I think is hard to learn, and when you´re learning it doesn´t sound very good heheheheh But when you get it, it´so beautiful!
But i think the acoustic guitar is good option for when you are hanging out with friend, say, at the park...you can take your guitar and jam. If you´re at home, you just take your guitar and play some tunes and it usually doesn´t bother anyone cause the sound is not loud like a violin, drums, piano.... And the sound that comes from the acoustic guitar can be so suiting and relaxing too....ah...maybe next semester
Do tickets run about the same there as here? $80-$100USD? I have to get a passport, so much to do, so little time!! September is not that far away! busybusybusy
