Bukit Timah or Bukit Merah

I have a friend called S. She called me 1 day to ask me about the direction for going to Bukit Merah from Tao Payoh. I asked her to go by CTE and exit from Bukit Merah.

She called me 10-20 minutes later to tell me that she is lost, she took the CTE and now she is at Yio Chu Kang !!!!. I told her that she is going in a wrong direction, she should try to go over to the other side of the expressway. She said ok.
She called me again 10-20 min later, this time she exit wrongly at Bukit Timah instead of Bukit Merah. I told her to take a taxi :(

Anyway this the picture captured by TP during her mis adventure. Yeah she took 2hrs to reach Bukit Merah from TPY.
