"Congratulations! You are the best!" read the card on the big bouquet of orange gerberas Mr Vincent Teo, 71, hugged to his chest as he waited to present them to Madam Halimah Yacob.
Mr Teo, who works in the social service sector, said he chose the sunny-hued flowers because they represent his hopes for the President-elect.
"The bright colour is like her, I hope she will bring brightness and cheer to Singapore and Singaporeans, and the country will continue to grow and prosper with her as president," he said.
The grassroots leader in Buona Vista said he had met Madam Halimah at several dialogue sessions, and is optimistic that she will be able to do more for the aged through her new role.
"Many people here are concerned about the economy and jobs, and more and more elderly are concerned about their future. I think she will make a difference because she is very caring. Through conversations with the Prime Minister and Government, she could give suggestions," he said.
