Why so personal?

I've been noticing since we moved to Sunshineville that there are a whole lot of people driving around with vanity plates on their cars. I've never had a vanity plate in all my many years of owning cars. Mister C had them on his Bananamobile before we moved here. He has a bright yellow SUV style vehicle and he used to have plates that said BANANAZ. I came up with this for him because, as I told him, he was nuts for buying this vehicle in the first place. However, a bright yellow vehicle with vanity plates in lieu of a 20 year old for his mid-life crisis works for me. I don't necessarily mind vanity plates in and of themselves. I just have issues when they make no sense to me. I can understand BANANAZ. It's readable as is. I don't have to sit at a traffic light sounding it out to get it. Just today I saw one that said NICU RN. Obviously a nurse that works in the neonatal intensive care unit. Makes sense to me and I didn't struggle to understand it. But what about HRD2HDL? I think that the 20 something blond behind the wheel of this cute car was trying to say "hard to handle". But where's the n? Who wants to be "hard to headle?" Or how about PLNAPRV? Does it mean "plan approval" like he's in the business of granting approval of building permits? Or does it say "plan a pervert"? Could go either way couldn't it? The last one I noted today said WHJD4U. My first thought, based on their fish emblem, was that at least the last part means "Jesus Died For You". But what about the first two letters? "Woo-Hoo Jesus Died For You!" seems to be a bit exuberant about the death of our Lord and Savior. "What Has Jesus Done For You" would work I guess. The main point here (and I do have one) is that if you're going to have a vanity plate, it should at least be somewhat obvious to the common man. I shouldn't spend my time trying to figure out your plate. You're obviously trying to send a message, so make it clear. If I ever do get a vanity plate, I'm going to make sure it's easy to read and obvious. It's going to say ACRONYM.
