But as a parliamentary member, she has now openly declared war against government MPs, a war that still persists.
Rosana turned her back on a project of House Speaker Chai Chidchob that would have deducted Bt2,000 from each parliamentary member and donated it to military and police officers killed or injured in conflicts on the Thai-Cambodian border.
Although Chai made the donation optional, Rosana said Chai, as House Speaker, should not interfere with senators. Rosana and her so-called "40 Senators" group could make their own donations to the officers.
It is clear the senator group is anti-government. And it would disapprove of anything moderated by the People Power Party-led government.
The group also decided senators should not get involved in the four-party meeting, or any movement to amend the Constitution, as it would be a parliamentary system-facilitated coup.
Rosana said the Senate is not a political party with a whip to direct it. The Senate Speaker or his deputy who attended the four-party meeting might not be the Senate's representatives.
The "40 Senators" group boycotted the convention on October 7 when the Cabinet declared its policies to Parliament. It was the day the People's Alliance for Democracy besieged Parliament before the police suppression.
On that day, Rosana's husband Santisuk Sophonsiri sneaked into the House when he saw People Power MPs walking towards his wife and abusing her. Earlier she had protested about the injuries to demonstrators, calling on the government to show responsibility by dissolving the House.
The couple was forced from the chamber floor and Santisuk was taken to the security director's room for investigation. Rosana defended her husband, saying he came into the chamber because he was concerned for her safety.
On Wednesday, she petitioned Parliament president, Chai, to investigate MPs' behaviour and ethics.
In the petition, she said Bangkok MP Pairoj Issaraseripong was rude to her. He pointed a finger in her face and said, "I'm telling you to stop your vicious conduct now. You are ruining the country, I am telling you, you are a burden for the country," she quoted the MP as saying.
On the other hand, 45 PPP MPs on Wednesday petitioned Senate Speaker Prasopsuk Boondet to investigate the behaviour of Rosana's husband Santisuk over his intrusion into the chamber. The group said October 7 was not the first time he had joined the Senate's meeting without authority.
It is time for Rosana to accept examination of her side; but the war has not reached its end.
