Sometimes you have to take some from your children, to buy the latest tools of trade;- I get them provided by the companies I work for, but if someone is in need of some help, I wouldn't hesitate to get off my high horse and lend them my hand. But hey, I've been told so at home, GOD bless them.
Cheers,
