BNP and JS

I am utterly disappointed by the BNP politicians. They got elected by the people and it is their sacred duty to attend parliamentary sessions to highlight the problems of the people of their elected areas. But instead, they are finding excuses not to attend JS sessions. People are unhappy with the attitude of these BNP members of parliament. Now they have come up with a 10-point demand in order to return to parliament. This is absurd and ridiculous.
If they have any grievances, then it is their task to go to parliament and highlight their issues. Before election did they ever say in public that even if they get elected and fail to form government they would not go to parliament?
