Playing with fire is used to refer to something that is dangerous or risky that could lead to you being harmed. So, if you run across the street when there is traffic coming, you are playing with fire!
I’ve been studying English in ACET for 6 months. In my experience, having studied English in a couple of different schools so far, I would like to say ACET is the best language school. Teachers are all very friendly and such good listeners and all staff is super nice and supportive. They set up various cultural events such as finding eggs on Easter, playing card games with tea and putting on costumes on st.patrick’s day & Halloween. All extra activities are really fun and I think all these things make students feel like home. And I met many classmates who are very satisfied with their courses here and took another course again. So I highly recommend ACET as a perfect language school to study English in Cork, Ireland.
