Fruit fruit fruit fruit

I love the pear tree on S College on my walk to campus. I'm always really tempted to pick one, because it's clear the people whose yard it's in aren't exactly harvesting them daily or anything. A bunch have fallen off and are rotting on the sidewalk, getting smashed by passers by, attracting fruit flies, causing all kinds of mess. And there are numerous low hanging branches, putting any number of pears easily within my reach. But would a pear from this mystical tree even taste good? Is there a reason nobody has picked these pears, whether just to consume or to try and make a profit like one of those old fat men who set up fruit & vegetable stands in the parking lot at Food Lion? If it tasted bad, or if it made me sick, would I wish I had just never taken one because being excited to walk by the tree every time I go that way and imagining its sweet juiciness in my mouth is so great? I used to say it's always better to experience and find things out, so at least you can have the satisfaction of knowing you tried rather than regretting not doing something. I don't know what I say now.
