My location is a closely guarded secret.
Okay, fine, I live in Limerick. The graffiti is on a wall in the Garryowen housing estate, near the dog track, and I assume it is referring to Northern Ireland. While I was growing up it used to have graffiti saying "UP THE IRA" and "NO EXTRADITION", but around 5 years ago the city council had the wall painted. About a year later the new graffiti appeared.
I completely forgot it was there when I walked past it one day on the way to the cathedral with that English girlfriend I mentioned up-thread. She got freaked out by it, spent the rest of the day worried over it and told me that she didn't think she'd ever fit in over here. When she went back to England she decided she was going to stay and be a teacher and never came back to Ireland. Although, in fairness, that probably had more to do with me being an asshole.
