If I had a twin, I think her name would be Joan. But spelt with a 'G'. Like me. Gillian and Goan.
Goan would be awesome. She would be totally funny and smart and pretty.
She wouldn't be one of those people who are unaware of their surroundings and just stop dead in front of you when they get off the escalator. Goan would know that you have got to get straight off the frickin' escalator or the people behind you will bang into you like lemmings falling off a cliff.
Goan would totally get that.
