Not all memories that were revisited were just as sweet, however.

For artist Eunice Hannah Lim, waiting for her mentee Foo Hui Wen at Tampines Changkat Community Club resurfaced memories of a somewhat fraught day when they were racing against the clock to complete a mural there before the next morning.

Lim, 34, remembered being “really furious” when Foo left midway through the project to meet some friends before returning hours later. “It was supposed to be her wall, and she needed to take responsibility and ownership,” Lim said.

For actor and content creator Dharmadasa D Dharamahsena, more commonly known as Das DD, his search took him to his childhood home in Teck Whye, where his parents got divorced.

“It doesn’t bring back really good memories,” the 36-year-old said. “But if I see my mother there, I feel maybe we could find closure in that space. Then we can remind each other that we’ve moved on.”
