A recent survey confirms that, thanks to the economic recession, people will spend less money on Dad this Father’s Day than in years past. But, in these materialistic times, the deprivation might prove a blessing. Tracy Mullin, president of the National Retail Federation, explains: “Gift givers will be looking into items that Dad can enjoy with the whole family” — grilling gear, sporting goods, lawn and garden stuff. What the business pro doesn’t mention, we will: Lots of “items” don’t cost a dime. Time, prayer and expressions of appreciation spring instantly to mind.
