Just a few interesting events... Yesterday, i got off Buona Vista MRT and was attempting to take 95, despite being turned down by what happened back on thursday (had to wait 30mins for it:()
So, i got to the other side of the road by the overhead brisge and made my way to the busstop that comes before the moe busstop(doesn't really matter, since they're of about the same dist.) But when i took the right turn, guess what i saw... 95. Wow. What a wonderful world...
And guess what i did... I turned around and took off. The people looking at me must have thought i've seen a ghost or something but ya.. i was trying to catch it at the MOe bus stop...
And of course, after some time, i did get to the bus stop. Again, guess what... 95 was no where to be seen!
And i had to wait several seconds before i saw it turning in..poor thing.. must have been stuck before the pedestrian crossing.. hahah (i'm also a poor thing lor.. could have just walked to the busstop...)
