Lol, it’s a big, big deal. Bonfires, dress up, trick or treat was all done as kids. It’s a bit different to tv version in America, but that has crept in over time. However, it’s always been a big deal as a festival.
Food is different - monkey nuts, barn brack (sweet bread) with a fainne (ring), cloth or coin to predict the future. The púca. Fireworks. Bonfires. Public holiday. School half term. Change of seasons.
