As you know, a number of guys here have to justify their bike-related purchases with their wives
"But hun, these wheel's weight 9/10th my last set and makes me a whole 8 seconds faster over a mile!... can you just IMAGINE what that would mean if I was in the Tee Dee Effffff ?"
For those who are in this position, here's the plan. Every morning you go to work, justify to your other half why you're going to work. Lay out all the reasons why you have to get your ass outta the bed each day. And dont just say "gotta pay the bills"... no no no. Just like your wife will scrutinize each part of your bike's purchase, so you should scrutinize each bill, really break it down. Gas, electricy, fuel, insurance, lay it all out to her. Do this every day you go to work, tell her your justification for going to work.
On the odd occasion you buy a bike/part/accessory, just lay that on her too. Go ahead and justify that. Hun, I gotta work to pay the insurance, the gas, the bike wheels, the fuel, the tax, the bar tape, the ... you get the point.
Me? I'm kinda lucky. I bought wheels, new clothing, a few other items, iphone, mac, another computer, my wife didn't bat an eye lid! It was great. So looks like I'm outta the justification phase. But for those who are still there, go forth and justify away. See how it goes. Report back here soon.
