Hmm, TS is a very sensitive person. the direction thread is going is just ugly.

here's my opinion.
there's always issues with oldest, youngest, only child,only daughter, only son.
that's how the society we live in works. there will always be discrimination, stereotype against what is considered abnormal in the society.

there's nothing wrong or sinful for being the only child in the family. its just how you live your live, how you face situations, and your abilities, talents that will ultimately be the decider of the social status you will be in.

and i think TS should know better than anyone else that there's no such thing as sin for being the only child. its all psychological. TS just have to get in touch with the subconscious realm of the mind (reading some psychology book will help you understand yourself)
