So there we were last night, watching Smallville on DVD, minding our own business after a pleasant dinner out with friends, when an almighty crack sounds and the glass in the sliding door shatters, imploding all over the carpet like buckshot! We crept over to investigate, half expecting a home invasion or at the very least a broken branch, but there was nothing and no one outside in the darkness. Glass man came to fix it up today. He didn’t even raise an eyebrow when we told him what had happened. Apparently glass can shatter apropos of nothing when there’s a sharp change in temperature. Especially old door glass like ours.Who’d have thought?
