Facebook Ettiquette

I've discovered that...

• Blinkymummy is a friend's cousin, and I know another cousin from my debating days.
  
• I may have gone to school with Tym's brother, but I'm not sure.
• Shyue Chou knows one of my AC Drama juniors.
• Shianux knows another of my AC Drama juniors.
• A lawyer I've used in a recent case is a 2nd degree contact, friend of an old JC buddy.
  
• Willie and a JC friend were neighbours in England.
  

This brings about an interesting question. What do I do for 2nd degree contacts that I know but not that well? In at least one case, I only know that person in her professional capacity but am close friends with our friend-in-common. In another case, I know the 2nd degree contact, but it's been years since we've spoken.

Decisions, decisions.
