Our house has all of it's original windows, the exception being the weird small one in the upstairs hall, but it's still wood. At first I HATED them, and couldn't wait to rip them out and replace them. But then they grew on me, and I learned (from here, and GardenWeb). Now, when I sit in my living room at just the right time of day, it's beautiful how the sun comes through and leaves a rippled pattern on the wall from the wavy glass.
But my friends won't understand, so when we talk about home improvement and windows come up I just nod my head and smile. One day when mine are all restored and look a hundred and one times better than theirs, and last longer, maybe then I'll speak up. But right now to them (and to me, sometimes) having happy restored windows seems like a pipe dream. I don't mention it to my parents anymore, either, because they don't "get it".
