When visiting a mosque or church in a Muslim country, be respectful as a woman of what they want you to wear. You may have to only cover your hair and dress modestly, but in some cases you will need to rent a chador. They rent outside of the location for a very small fee. Both genders will be required to take off their shoes. Be respectful :)
One day I went into my room and saw my favorite Vocaloid poster (which Vocaloid is one of the most important things to me ever) completely ripped. I have no idea what the hell happened to it and I was so upset I cried about it.
