And then there's deciding whether to go by Kate, Katie or Kathy, and all the different ways of spelling Kate, Katie and Kathy. And if you go by Kathy, people don't know if it's short for Katherine or Kathleen. I'm glad my mom decided to name my sister after my grandmother Katherine instead of me! Everyone always has to ask how she spells it.

There's no confusion if you're named nicknames and pretty much only one way to spell it. Unless you really want to count something weird like Iryss or Irice, and Rissie for short. I don't think that exists in real life though.

Interesting thoughts, Iris. As for Bob, I'm glad your parents choose the single-o spelling. Whether you put an extra o in the middle or at the end, it doesn't seem good, though I've met my fair share of people who can best be described as double-o'ed Bobs. The ways of spelling Bob are numerous if you allow things such as Baughbbe.
