On the subject of picture taking..
Some guy came up to me with his camera asking me something and motioning it towards me, So I step back, hand my stuff to my sister and proceed to get into my pose (one that involved my eyes closed). After a while of standing in the middle of the walkway with my arms out, I notice no flash going off and I hear my sister say " You dummy, He wants you to take a picture of him!" I was just like "Oh!..uh..Ok!" and I took his picture. I felt so stupid.
Lesson: LISTEN to people when they are asking you questions, don't assume they all want a picture of you. -_-;
