>plumbing
Yes. The family business is a small electrical and plumbing wholesale distributorship. I'm 1/3rd owner but -since 1999- largely inactive in management except for 'overview' items such as audits, tax, legal, insurance, etc.
add to that "construction"
About 40 years ago the business forked and subsequently split into commercial real estate development --we did our own building.
Between the 2 businesses above, I grew up immersed in the trades. So up to and including light commercial work, yeah, I can plumb with the best of them. Wiring, too.
What's that they say? Jack of all trades, but master of none.
