MEN, grab your calculators!
Add up the cost of all your gear. (This may be shocking to her at first) Pull up ads for similar gear for sale on the net ... subtract that number from yours. Remember this number!
Now take your neighbors fishing boat, add gas for each time out, beer, insurance, repairs, storage and travel expenses for trips they might take. Find a similar boat for sale on the net, subtract that number, and see which hobby is really more expensive!
You can do this with golfing too. Add the greens fees, travel, CC Membership, dinner and beer for the amount of time you have owned your audio equipment ... a 5 year total is amazing. Now try to re-sell that and see what you are left with!
Now, if you are looking to get divorced, ask your wife for all the receipts she has for misc. expenses for the same time period, add those up ... check to see what you can re-sell those items for, and subtract that number from the total! Need I say more??????
Liars figure, but figures don't lie!
