You Mean Your Friend as in SBS2779A =P
Move to the main point. We need to check who else took that train,
by checking what is the serial no. on the train that reach Paya
Lebar at 10.45pm, then we can know how did they thought about
that.
By the way, I think the tracks had turned to normal, as I took
trains from Bishan to Paya Lebar & vice versa today between
9.45pm - noon.
