Looking for an idiom that describe such situation that one event entails another. I.e., describing mostly for troublesome/negative events that comes one-after-another. "long-tailed"?
- to explain "Z", then I have to first to explain "Y", which depends on understanding of "X", which builds on top of "W", ...
- or, it's like pulling up a huge carrot -- the more you pull, yet the more it seems are still missing.
I.e., once started, problems come one-after-another. Any idiom for this? Thanks
