It's a small small island

Yesterday, while meeting up with a few colleagues to go Pulau Ubin, I noticed a group of Scouts also meeting up at CCK MRT seemingly packed and ready for a camp. They left on the train earlier as I was still waiting for another late comer.

When we finally set off, I was told we have to wait at Tiong Bahru station for another colleague, zzz, another late comer...

When we alight at Tenah Merah MRT, and got to the bus stop, and there's the same group of Scouts, and boarded the same bus headed for the same destination.
