Advice for an oblivious girl!

Ok so this is going to sound either mean or wierd. My best friend (Nadine's) good friend (Danielle) is a nice girl, she means well. However she has no idea how to interact with other females. She has only had a couple of female friends in her life and she is 25. My friend suggested that we put together a sort of a manual for her (and she wants us to). A manual that will outline the do's and dont's of being a good friend. Kind of a what to do and a what not to do. She is very inappropriate and she does not think before she speaks.

ex. of her behavior- One night we were out at a club with Nadine and Danielle's coworkers. ANother good friend of ours, Mindy was out. When Mindy gets drunk she does inappropriate things with guys she barely knows. We all know this but this does not need to be verbalized with everyone- especially Nadine and Mindy's coworkers (nadine and danielle became friends in college - they now work together in a corporate setting. Mindy was talking to Danielle and Nadine's coworker when Danielle came up and advised the guys Mindy was talking too to be careful because Mindy gets drunk and likes to sleep with guys she doesn't know.

another ex. Nadine and Danielle are both somewhat heavy. Nadine carries her weight well - and has curves, however Danielle does not- Danielles weight is in her midsection and neck. Nadine was upset about her weight and was trying to find an outfit to wear when Danielle made a comment about Nadine being heavy and that she was insulted because somebody said that they had the same figure. She actually said this to Nadine. Meanwhile Danielle looks heavier than Nadine because of the way she carries her weight.

In additional Danielle does not know when to leave things alone, when and where to approach sore subjects. Danielle does not think before she speaks. Danielle has had a couple of pathetic realtionships with pathetic guys and she attempts to dish out advice. She is in competetion with Nadine with everything- she always wants to have one up. If Danielle buys an article of clothing, it is only because Nadine already purchased it.

Danielle means well- she is not ill spirited she is just oblivious.

Does anybody have any advice for this little manual.
