Well, being a regular in three different galleries, yep I can recognize SOs, DHs, DWs, DDs, DSs, pets and now even nieces and nephews.
Cute story: Melissa Lewis and bderby are sisters and one time bderby scrapped a photo of Melissa's DD Rory! I was like "Hey wait, why is she scrapping Rory!" I even commented in the comments something like - Isn't this Melissa's Rory? She sent me a PM telling me that she was Rory's aunt and just loved scapping photos of her! LOL I felt so stupid because I forgot that she was Melissa's sister and of course she would scrap her absolutely adorable niece!!
