I am gonna use some harsh words here....
For those of you who do not understand a wee bit about OCD or Autism, can you all please shut up!!
You can read articles, search Wikipedia or see YouTube, but unless you have been a caregiver yourself, you will never be able to fully understand what such type of conditions are all about. (Even caregivers also will not understand it, let me tell you all)
I am a parent of an autistic kid, and I think many of the above comments are hurting, baseless and needless. Please don't think that by reading up over Internet, you will understand what that condition is all about. You all don't, so please don't think you know all. (you all know who you are)
Let me tell everyone, even the doctors also can't really explain the cause of the condition, and they are basing intervention based on researches done by earlier batches. Only the affected person knows what the condition is all about. And I think Silas has already mentioned it in another thread.
Lastly, in this world, not everyone is fortunate to be as normal as "YOU". Count your blessings that you belong to that group. But never forget what happens to others may also happen to you (or next generation) also!
