Same, yeah, it's rewarding. Firstly, I put down fun due to the guy's portrayal within the image, however, I then thought about the tedious work involved in volunteering, especially in the aid of others. So then, i said to myself, "How the hell can sleeping in foreign countries with minimal food and hardly any shelter be fun?" After that, I quickly put an X over fun and put down "Rewarding".
I had a huge debate with my english teacher over it, with her believing it's "fun". After the controversial argument, she re-analysed the question by using her logic, and stated that I was right, and apologised for her misunderstanding. LOL!!
