I have to ask
What's the big deal? So what if someone wants their laundry pair to match. I bought matching pairs last time, I probably wouldn't have but there was a sale going on and I got the dryer for "free" when buying the washer. Otherwise I may not have bought the dryer. Though I did, at the time, want the steam dryer. I hardly ever use steam. In fact, I hardly ever use the dryer when weather permits.
So I do hereby decree, it is ok to have a matching washer and dryer if you want them.
