Jean-Eric Vergne said there was no point in being angry at Michael Schumacher, despite feeling that he lost a seventh-placed finish in the Singapore Grand Prix because of the German.
The seven-time world champion crashed into the back of Vergne's Toro Rosso on lap 38 after the appearing to leave his braking too late.
Schumacher said afterwards that Button finished second he thought a mechanical failure had caused the accident.
Vergne was philosophical about the crash.
"I was focusing on catching Sergio Perez at that point, trying to brake late to catch him, so I am not too sure what happened exactly, but I assume Michael braked a bit too late and could not avoid running in to me," said Vergne.
"There is no sense in being angry about it, because these things happen in racing and even the most experienced driver on the grid can make mistakes! He said sorry and that's the end of it."
The Frenchman, however, felt his retirement cost him the chance of finishing as high as seventh.
"Overall, I am very happy with the way this weekend went, because I personally made a lot of progress from Friday through to tonight. The team also worked very well to improve the car throughout the three days.
"It's just a shame it did not end with the points for eighth or maybe even seventh place."
His team-mate Daniel Ricciardo finished in ninth to give Toro Rosso its second helping of points in three races.
