Child molesters

So last night, Heather, Chelsea, and I decided to go out to dinner at El Toreador, our local neighborhood mexican restaurant. Our first strange encounter was an extremely drunk man in his 60's who came up to us while we were fucking around outside, waiting for a table. I assume he stumbled down from the neighboring pub, Joxer Daly's. He approached us and said, "Can I ask you a question? I'm not a bad guy or anything." He asks how old we are and we tell him, and the following 15 minutes are a blur of slurred life advice, culminating in this little nugget of wisdom,"...and have as much sex and possible, with as many people as possible. But only with me." He then stumbled off and we ran screaming into the restaurant.

You'd think we were safe. Oh, no. A group of four people walk out: two women and behind them, their husbands. We're sitting in the waiting area and the two men (clearly in their 40's) come over say, "Hey, you should come have a drink with us next door." We laugh nervously and mutter after they leave. Another group of men (also in their 40's) walk out and one comes right up to Heather and says, "Let me guess. Vicky. Hahahahaha." The only pleasant coming-on was three stoned surfers from Santa Cruz who were jealous that we were so far ahead on the waiting list.

So here's my question: Why do old men find it appropriate to hit on little girls? I'll clarify this by saying that all three of us were wearing jeans, sweaters, and big jackets with scarves, and Ugg boots because it was freezing outside. There was nothing maturely sexual about us. So what the fuck? You could be my father. For all I know that old man could've been my grandfather.
