The best thing about travelling is observing the way lives are led in other countries, and appreciating what you already have in yours. There's no better way to learn and live than to travel (especially on a limited budget! :p)
I'm making it a point to learn other major languages because if I have to fall back on charades and drawings to communicate, it will be an epic fail :p.
Oh by the way, I've decided to put on the hijab recently - just didn't manage to change my profile picture to reflect that. Thought I'd let you know in case you'd get a shock when you meet me :).
