Quoted from AntennaMan:
I've never met a wife who'd want a man to keep a pin, even though I've heard they exist.
I asked mine if I could get another pin even though I have 5 project pins and I am 2 pins above my limit...limit imposed because it's what I have room for. She asks me, "Can you get the cash to buy it? If so then go for it!" Best wife ever!!! They do exist!
