I think we were

As the night deepened, the chairman had to come on the stage to thank everyone for making time for him. It wasn't as late for the young ones, but the chairman already overstayed in his own party. He expressed his gratitude and wished everyone an enjoyable night, and then personally bid a few a farewell. 

Since many of the chairman's personal invitees were busy men, they also had to go. Hence, Vincent, together with Fil, had to send them off as the chairman's grandson and host of the party and Fil, because the chairman asked her to walk him out. 

"Filomena." The chairman held Fil's hand gently. "I am sincerely grateful that I could share this day with you."

Fil's heart warmed up, holding the chairman's hand affectionately. "Chairman, it is me who is grateful to be here. Please take care on your way home."
