When my kids were young I traveled for a living - kinda Willy Loman style - and while traveling I would always pick up pens, notepads, candy from hotels, conferences, sales meetings, customer events etc - and bring them home to my kids. At a young enough age they thought this was great!!
Well the kids got older and the trinkets brought back from my travels did not hold the same fascination as they did when they were little. UNTIL they went off to college and I would send them pens, paper and an occasional US currency bill along with a note explaining that these were "Schoolin Supplies"
Now they are all graduated and in the work world - however, as I returned from a trip today from Tuscaloosa, via Houston, to ClevLand - there waiting at my front door was a box of much needed supplies for my apartment. My son collected these goodies from a Trade Fair in the North East and sent them via USPS with a note - Hey Dad, For all the years of hotel pens, It's payback time. Ha Ha. Love Although I will put them to good use - I still have not found the $20 bill.
