continuous stare

Description

this happened last month when i was going back home from college and it was raining heavily and trains were empty so after i entered the train it occurred to me that i was the only person in that dabba, there was a another boggie beside where few men were standing and during the course of travel i could sense someone staring at me continuously, when i looked around i saw a guy around late 20's staring at me, even when i looked at him he wont stop staring and would give these ugly smiles which would freak me out i eventually started ignoring.
