You mean your wife has no Coach purse? > Nope. We tend to use such monies in more useful ways. For example as a donation to Guide Dogs for the Blind, after getting a trainee dog that had to be realeased because of a medical condition and that my wife then got through the therapy dog test. Now the two are serving Alzheimer patients (wife went to training yesterday, with dog, also costs a fee), nursing homes, schools, libraries and so on. There is no monetary ROI but it's rewarding in many other ways. Now I don't write this to brag, just so that (hopefully) someone reads it and thinks about doing something similar. Tons of opportunities. > Life is all about having the right toys.
