A: Can you help me build this bookshelf after work? I bought it from IKEA yesterday.

B: Sure. According to the instructions, building it should be a doddle.

Note: “A doddle” refers to something that is very easy or effortless to do or accomplish. The informal usage is primarily heard in the U.K. and Australia. For example: I found maths to be a complete doddle in secondary school, so I was taken aback by how hard it was for me in university.
