Zavier's mind ran amuck as he tried to think of any excuses as to what he was doing here. If the older man called him out, Zavier knew he would lose.
Of course Zavier could argue that the older man had been peeping as well, but then it would be his word against the older man's. Zavier could already see how this was going to pan out. Here was a horny teenager hidden in the bushes in the middle of the night, and on the other hand was a respectable looking man in a well dressed suit. It wouldn't go well at all.
It seemed like the thing he feared most was finally about to happen. He was about to be exposed as a creep, and he was none the worse for it. Zavier watched with horrid expression as the man lifted up his finger to his lips and gestured the sign for silence. What? What was happening? Zavier thought to himself.
