As a studnet  you have very limited options when it comes to food especilaly if you dont cook .But  i havee seen and been  to people's houses here in USA  who do  traditional Laxmi Puja and Gai puja       and at the same time   serve  beef items while playinhg taas later that night after 12:00 mindnight .I ts in your beliefs  .  i chose to Eat beef coz i went to christian schhol when i was a kid in India    i avoided it    it took some time to get used to it but now in US  im used to it.When i go back to nepal  I know  its a  sin there  ,although i had heard sumthin about  gai being killed  and eaten somehere in ktm. Its nothing about disrespecting your mother , According to the situation  and surrounding i adjusted myself. I have few friends here who avoid beef 100% nomatter what ,i respect them for thier choice.
