Best to tread carefully lest you find yourself skating on thin ice!
Oooh, there’s a lot going on here, so let’s get started:
1. Tread carefully: 1. proceed with caution so you don’t make a mistake 2. watch where you step/skate so you don’t fall over/go under the ice.
2. Lest: what a great word this is! It’s an Old English conjunction, which you could substitute with ‘in case’ or ‘so that you don’t’ or something similar.
3. Skating on thin ice: 1. to do something risky that might end badly 2. to skate on ice that’s too thin to support your weight!
