Sarah was thinking who could match that description... There is a lot of male students at the University, but only one stands out with his skills.
'Any person with above average skills can find a lot about me just by looking at some articles online and student information, but there is no way for him to find out that I'm looking into Philip and Mimi... unless...' Sarah looked at the bangle on her left wrist and started rotating it... she traced with her index finger each symbol: 'Alpha, Beta, Gamma, Delta, Epsilon... Rho, Sigma, Tau... Chi, Phi, Omega' Sarah noticed that Omega is larger than other symbols. 'How come I didn't notice this earlier?' She went back from the beginning comparing symbols and observed that Sigma is also larger... 'So out of all the symbols, only Sigma and Omega are larger? ... How come I didn't notice this earlier?!!'
Sarah was scolding herself for being blind. For ignoring the obvious.
