Each of us has a sob story about one time where we either ignored or skim-read the small print and it bit us on the backside.
Contracts are particularly dangerous for this. All that tiny writing, all that jargon...
But it's not just contracts and other important admin that we should be perusing with an eagle eye.
After posting about the warning on a bottle of Lenor's Spring Awakening fabric softener one woman has left - literally - thousands of parents reeling from what she discovered.
Leah Reilly posted on Facebook : "Never seen this before but all mums need to know DO NOT PUT THIS ON YOUR KIDS SLEEPWEAR!!! Look there's a f**king warning on the back of the bottle!!!!!"
Interestingly, this particular brand of fabric softener is one of a handful of items which cleaning guru Mrs Hinch swears by.
So, given the recent arrival of baby son Ronnie, we hope she's reading this.
The back of the bottle states: "Do not use this product: On children's sleepwear or garments labelled as flame resistant as it may reduce flame resistance."
Offering a more detailed explanation, one grateful commenter added: "It rids the flame retardant off items after so long, so in a house fire you will have half or even less than half the time to get out of the house before everything that everyone sprays Lenor on is ablaze.
"It's scary I don't know why people are even joking about this."
