Yeah, there's nothing wrong with chit chat, but when that chit chat is the revolving around the same topics day in and day out it can become quite mundane, especially when those topics are mostly about celebrity gossip and other such nonsense, haha.
I understand your reluctance to discuss drugs when you admittedly have little knowledge about the topic, most people will gladly speak about such things regardless of how much they know (I think it's because they always think they know everything). Also, I doubt your views on the subject would offend anyone.
Oh yes!!! that's exactly it! and I'm generally a really open minded person with not many fixed views as I understand that the world is filled with different opinions and perspectives, but yes a lot of intelligent people seem to think they know everything but there are so many things to learn in the world ^^ I only know about medical drugs like Gerozac fluoxetine which is an anti depressant and some others as well but that would be as far as my knowledge can take me >_<
I've been fascinated by drugs, both pharmaceutical and otherwise, from an early age so I've learned a lot about them, I could talk about them for days, haha.
But anyway you've a good head on your shoulders and this little conversation has been quite refreshing for me so thanks for putting up with my ramblings, haha.
