Thoughts on Names (Part 1)...You Need Not Agree

Chuck is short for Charlie...Why?
And Rob is short for Robert but Bob is not short for Bobert.  Who did that?
Why would you give your child two first names or two last names?  That's just confusing, especially if they are in the military.
Why do people choose to give normal names odd spellings – i.e. Cerah, Erryka – and then get upset when no one spells them right?
