I know this probably isn't anybody's idea of a massive breach of etiquette but I would like your opinions for future reference.
A few years ago, my DH and I along with another couple decided to take advantage of the local art museum's free admission day. No one couple invited the other - it was just a mutual "hey, let's get together and check this out" kind of thing. The museum is set up like many others - about 10 smaller rooms, separated by walls, but connected by large open doors. The show was a wonderful exhibit on Auguste Rodin and included videos on modern-day sculpture making. Well, I kind of got a little immersed in reading all the cards attached for each piece and looking at the details of the sculptures and maybe I watched the video a little too long and lost track of the rest of my party among the various rooms. After I felt I'd gotten my fill, I headed for the exit to the exhibit where I found DH and the other couple sitting on a bench outside. OC didn't seem put out but I could tell DH was irked. When I asked how long they had been waiting DH said "quite a while" but couldn't give me an actual time frame.
The reason I thought about this again was that we were initially planning to check out another exhibit at the same museum but with another couple this weekend. I made a joke that DH better warn the new couple that I like to read every word on the cards at art exhibits. "Yes, that was very rude of you to make our friends wait on you like at the Rodin exhibit," he said. Oh.
So my question is: when you're visiting an art museum as a member of a group, what is the polite form? Travel from room to room sticking to the group or split up as if you were individual patrons to go at your own pace?
It turns out that the new couple can't make the event this weekend so I'm just asking so that I'm not rude if this comes up again.
