「おかえり」と「ただいま」

So I went to the language table at Forbes today and met Tameyori Sensei.  ^.^  She said 「お帰り」（おかえり）(Welcome back!) to me when I got back from getting my アイスクリーム <3. That reminded me of this song called 「お帰り」that I really liked, but I never really understood what it meant until now, cause I never pay attention to lyrics when I listen to songs haha =P. It's the theme song of the drama 「絶対彼氏」（ぜったいかれし）(Absolute Boyfriend), which I also really liked. The singer is 絢香 (Ayaka).

Tameyori Sensei also told me that I'm supposed to say 「ただいま」(I'm back!) in response to 「おかえり」. I find them pretty useful phrases. :]
