"My pet dog died..."
"Oh, I'm so sorry!"
"Why? It isn't YOUR fault"
"Oh, Sharen... That's so sweet of you but we both know what I did."
"My aunt's apartment was on fire this weekend! She's in the hospital..."
"Oh Veronica, I'm so sorry about that!"
"It wasn't your fault, so don't apologize"
"Oh! I didn't tell you? Well... This is awkward..."
It annoys me so much when people interpret an oh-so-obviously sympathetic "I'm sorry" as an apology, so I've started responding by making it one.
The reactions are just pure GOLD :3
