Thread starter: the title of your thread made me laugh. Its immature, offensive, and I dont mean to sound harsh - but it is rather stupid.
Dont feel "sad" for older unmarried girls - a lot of them are much happier and prosperous than the happy younger married girls. Being married and breeding doesnt automatically mean that you have made it in life, for many there is much more to it.
A word of advice/request, the next time you feel like feeling sorry for someone in public forums - dont.
If you have to feel sorry, then feel sorry for those who have been deprived of their right to live, and instead of posting threads to air your sorrow - ACT.
Zabardast.
