Sentience in a seed-pod

I just finished making myself tea in a glass. The last time i had tea in a glass I must have been around eight years old. It's nothing special. Just tea. In a glass. But it tastes completely different. Kids, try this at home.

It got me to thinking how much of a treat this was for me when I was a kid. It was like catnip to a pussy. But I couldn't have this every day. My parents cautioned me that tea in a glass should be enjoyed carefully and in moderation. This was because (drum roll please) dumping hot liquid into cold glasses can make them crack, and then you have to throw out the glass.

Now that I'm big, I go through glasses all the time. Hell, I lost all my glasses, not to mention crockery, when my cupboard fell off the wall. I break at least a glass a month and it doesn't matter. I buy more glasses. But back at home breaking a glass was a HUGE deal. In fact, my earliest memory of subterfuge was me hiding a broken glass in the back garden so I didn't have to come clean that I broke it. Back then I understood this principle as law; now I just don't get it. My parents had a lot of cookey rules like this - couldn't use a teabag for just one cup of tea, couldn't run around on the front lawn naked - you know, things I do all the time now! Makes me wonder just what craziness my kids may have to endure.
