Tonight, or last night, I attended a barbecue.
Tired but happy,
because I learned some knowledge.
For example,
we all know that Muslims don't eat pork,
but not all of us know that they don't eat non-halal-meat, either.
To make halal-meat, those animals such as cattle and sheep,
must be slaughtered and processed according to Islamic customs,
and the meat must be separately stored, transported and sold.
So, a Muslim, who attended our BBQ,
brought some halal-beef and halal-chicken for himself.
