I gave my two money but wanted them to have a keepsake too so my daughter picked out some silver Jewelry and I bought my son a good watch. My 2nd son's 21st is coming up and I am at a loss as he already got a nice watch and wouldn't wear Jewelry I am thinking of somehing in leather like a filofax. I know some people give holidays but the money I give them would allow them to do that I just want them to have something to say they got for their 21st if they choose to keep it. I know I got a ring from my parents and I still have it and treasure it.
