My FH and I are long distance for now, he's stationed in NM and I'm in MD.  We have had a terrible time making a registry.  I've lived on my own for 4+ years so I have most things in my home that I need, and we're not into registering for lots of stuff that we won't uses.  Since we're LD and have a small registry is it rude to have on the shower invites something like "Help the couple spend time together with a southwest gift card"  Might need to work on the wording... but you get my drift.  Is this ok to do?
