Do it yourself tombstones?

So today my sister Cari and I were shopping around at Kohl's and we found this really neat decorative cross. We automatically thought of my mom (she has a cross collection). This particular cross was different than any that she has. It's a celtic-like cross and it's pretty large--it's meant to set outside in a garden. Long story short=it's a cool cross. Anyhoo, we decide to buy this for our parents as part of an anniversary gift (26 years! go mom and dad!). So, we get up to the check out line and the wierdest conversation with the cashier follows:

Cashier: "Is this for the garden?" (pointing to the cross)

Me: "Yeah."

Cashier: "Oh." (puzzled look)

Me: "yup..."

Cashier: "In the country where I'm from you would put this on your grave. So, if you would have said that this was going in the cemetary, that would have been okay, but going in your garden? That's strange." (looks at me funny)

Cari & I: Confused look, then smile and nod, continue to head for the door.

Cari: "So, let me get this straight: if we are coming to Kohl's to build our own headstones, that's okay--but if we're here for garden accessories, that's strange?" Hmmm...
