I was on the bus this morning, on my usual way to work. Seated beside me was this guy in business attire. Nothing unusual so far. I was minding my own business, plugged into my discman when he decided to take an interest in staring at me.
Everything I did, he stared...
Sent an SMS to my colleague, he stared at my phone and attempted to see what I was typing. Changed my CD, he stared.
Looked out of the window, he stared (I saw him from the corner of my eye).
I was so freakin' pissed, I looked back at him and he just stared back at me ! *duh*
Continued staring at me once every 10 secs until I hit upon a wonderful idea.
I typed this SMS to my colleague :
" Why do idiots sitting beside you on the bus enjoy staring at you when they can just mind their own f***ing business ? "
It worked momentarily because he looked away after reading my msg (held the phone in such a way he could read the message!).
After 30 secs, he was at it again... 
My question : What do you do in such a situation ? I was quite tempted to slap him actually. I couldn't get away from the seat because it was a very crowded bus and I was seated at the corner at the back of the bus.
PS. No, I wasn't wearing anything remotely sexy or short !
