Cross-server PUG culture shock

From my lovely wife on Google chat just now:

“We’ve been doing new dungeons but keep having to pick up one cross-server DPS.  I don’t think ‘Grampywraith’ was quite prepared for me and Jemjabari RPing our way across the Pit of Saron.

‘Jemjabari.  You may be somewhat confused.  The skulls are NOT YOUR FRIENDS.’  <pause> ‘Please stop petting them.'”
