I wonder what changes people. Especially in matters of principles and religion.
What, for example, would change a demure conservative kampung girl into a wine-drinking, pissed-at-the-pub type. NOT that I know anyone like that. It is, an example, like I mentioned.
What drives a person, to do or decide to do something that has been instilled into him/her as wrong?
Stealing is wrong. Killing is wrong. - so you know you won't do it.
Is it any different with drinking or sleeping around? Surely the principle is the same.
Was it hard the first time you took that glass of wine in your hand and drank it, I wonder? For surely you have been raised a good Muslim - if not by your parents, then you were taught by your teachers.
Was it the pressure of friends, or were you simply curious or were you ashamed of being labelled a prude for not drinking? Maybe if you didn't join in the fun, bosses would pass you over for the promotion or project you were eyeing.
It is a hard thing to do to be a good Muslim nowadays.
