It is a bad idea for me to carry cash.  If someone comes by raising money to treat nail fungus in chimeric tigers in Bangladesh, I’m in.  Someone near and dear to me balances me out very well.  When I was recently gathering up donation items for hurricane victims in Timbuktu to take to a drive at work, he came through and did a last minute rescue of everything he could possibly use, disposable razors, packets of new underwear, T-shirts, socks, soap, and deodorant, leaving a few items he had no real use for:  hand lotion, multivitamins, and pantiliners.  It takes all kinds.
