He stands across the street keeping to the shadows. He waits. He found his target and now is the fun part. He doesnt like to rush into anything, now is the time to continuing being patient, he knows his target thinks that he's safe. 

The man smiles as two young men get out of a cab. He can hear their voices echo across the street to him, full of joy and teasing. They are happy and laughing, holding hands and leaning in for a kiss.

The man scowls at them, their happiness casting a dark shadow on his mood. He watches as his target, the taller of the two, tugs on the others hand pulling him towards the apartment with a laugh. An idea forms in the mans mind and his lips curl into a smile. 

He has them just where he wants them.
