We were all new fumbling/floundering divers once lets not forget that or think otherwise.
When it comes down to being buddied up with a new or a inexperienced diver on a vacation. I have no problem with this. You can be cert for 10 years and having only 8 dives under your belt, you're not experienced. In fact I prefer I be the one instead of my other travel companions. I'll introduce myself, talk to the diver Usually I can finish the dive with them and then link up with the other remaining divers and still have a great dive. After making a dive with a resort boat the DM's usually ask me to do this buddy thing anyway so I make the best of it and try to really let the buddy have a great experience, From that I enjoy the dive especially when there is something new they (or Me ) see for the first. Just like a kid at Christmas (BY THE WAY MERRY CHRISTMAS EVERYONE!)
