LOST!

This morning I wanted to go suntec but I lazy walk and don't want to talk circle line because it is expensive, so I alighted at orchard station and walk over to tangs bus stop and I took bus 700 because I thought the bus got go to suntec but it never. It brought me to shenton way and I alighted at OPP. MAS Building bus stop. I am totally lost and don't know turn left or right, trying to get myself back to suntec, in the end i took a cab back to suntec. x.x
