try to get something you know he will use...
the Lowe's gift certificate is a GREAT idea!!!
i know every year relatives give my dad things that lay around..
but the man uses undershirts and socks and around the house clothes more than anyone i know..
he works alot in the garden and aroud the house and he tears up thigns constantly..
sooo i got him a big box of socks and undershirts and some around the house tshirts...its things that he wouldnt normally go get himself since he thinks wearing the same ratty shirt with holes and stains is ok..
but he's got me to get him new ones!! thats what daughters are for right
