I don't really care for this holiday. Corned beef is alright if you put it in a Reuben, and Guinness is the most overrated beer on the planet.
This is the greatest holiday ever. All you are required to do is have fun. You don't have to be romantic. You don't have to buy gifts. You don't have to hang out with relatives if you don't want too.
All you have to do is have fun.
One thing about living where I am is there is a local cafe that serves corned beef and cabbage that is absolutely to die for. Even people who usually don't like it crave this guy's food.
Guinness? Naaaa....you don't need to drink that. Drink what you want.
