Hi..I think Asians are more family oriented therefore more interested in others things unlike the westerners who are cold..I am an Asian and I too find this nature of our fellow asians very irritating..But cant help it,that is how our community works coz Asians love to poke their nose..
The only way 'mom me' u can react is politely tell them that it is something personal and u dont want to discuss it..and BTW u say u r a proud south east asian,then why is that u want to find an answer for this since u know very well how Asians are
