People says "don't mock others", right. Who knows if that thing we mocked about, could happen to us, or our children. My dad was a teacher (he's retired now), so he's kinda strict when teaching how to read Al-Quran.. he often scold people who couldn't pronounce a certain letter correctly. For example, the Arabic letter 'ra' and 'gha'. So once (or perhaps many times behind his back), his pupils say 'you just see.. you'd know how hard it is if your own kids have that difficulty too'.
Things just happen the way it did, so I'm just glad I got better =)) ..as i myself have had this hardship before, that gives me the right to brag about it, and mock others who cannot say 'R' correctly, right? XDD
