I am obviously U for asking in AIBU but I’ll crack up coz I spend my life doing this. Me word recall as well as my spag has gone to shit basically, (it’s a brain problem sadly)
There is a word for something that you think will take 5 mins and ends up taking 2 hrs for example. Something that for spefically how long the task took, (apart from “divorce” 
)pretty sure it begins with e but poss not 
like an expectation versus reality but just for the time it tiok.
please help, any suggestions welcome. Thank you!
