Not accustomed to losing consecutive games, Iain Henderson believes Ulster must use their hurt as a spur towards victory when Exeter Chiefs visit Kingspan Stadium on Saturday evening.
If Ulster had managed to hold out for eight more minutes when leading at the Stade Chaban Delmas, we likely would still be talking about a defensive stand for the ages.
Close, however, counts in horseshoes, not rugby, and the irritation in Henderson's voice is still evident days later when discussing the late collapse.
"Frustration," he replied simply when asked what has been the over-riding emotion of this week's preparations.
"We defended so well if not for stupid errors that nine times out of 10 most of our players don't make. That's what's so annoying.
"The positives that came out of the game were outweighed by really, really stupid negatives.
"That's brought massive frustration to the whole team but we've got to use it, put it behind us and focus on Exeter."
