OFFICIAL Card - Taiwan

Jane sent this card showing the Beitou branch of the Taipei Public Library located in Taipei city. She writes that it is designed to look like a ship and is entirely "green" using solar energy to power the branch, collecting rain water to water flowers, etc. It looks like a wonderful building.

On a totally side note, she "apologised" for her English, which I thought was perfect. As someone who only speaks one language, I just don't get why someone who is able to speak two or more needs to apologise if their second or third tongue isn't perfect. Anything is better than my one! Do you speak more than one language? Do you "apologise" to a native speaker if you feel your skills aren't "perfect"? Trying to better understand it.
