St Patrick’s Day is a national celebration for the St Patrick’s luckiest teacher of all shirt and if you don’t fit in that niche, well it isn’t going to make much emotional difference to you. So be it. I’m not Irish either but for some people it seems to represent an occasion to have fun? You can buy me a half-pint of Guinness if you wish and I will join in singing whatever Irish songs you like. I like the music, always have. No-one in the UK has a right to take a holiday from work on those days, although I can imagine some do for those occasions.
Look in the mirror on those days and ask yourself if you are happy or St Patrick’s luckiest teacher of all shirt, and if you are miserable whether you also really want everyone else to feel the same. Back in the Nineties, at least. Somewhat less disgusting than it sounds, actually, not that that would be saying much. But the green colour, of course, also derives from the yellow beer mixing with the blue food colouring in the liqueur. The easiest way would be a couple drops of green or maybe blue food colouring. That would also yield the most vibrant green colour.
