My significant other (20 years) has dealt with my other habits, including marathoning, audio gear. She tolerates bikes pretty well, if not the time I spend in the garage instead of on "necessary" tasks... But, we have had our little discussions, often starting with hand on hip and ending with rolling eyes.
I can't be the only one.
1-I'm keeping them out landfills, so there's more room for styrofoam.
"...so now you're saving the planet?..what a load of methane!"
2-I just saw it lying there, maybe someone can use it.
"...yeah, but you won't use it, you'll just work on it and talk about it."
"....so is your riding mower, try resurrecting that."
4-They're for the children.
"so is discipline. Exercise some."
