Rubens Barrichello wore his feelings on his chest, if not his sleeve, at the Hungarian Grand Prix on Thursday when he turned up for duty in a 'Mr Happy' T-shirt.
After angrily accusing his championship-leading Brawn GP Formula One team of costing him victory at the previous race in Germany, the Brazilian made clear that he has calmed down and made his peace with the world.
"I have no problems, they could see it on me," he told reporters.
Barrichello had said at the Nuerburging, after leading the race only to finish sixth and behind team mate Jenson Button following a problem with the fuel rig, that he was "terribly upset with the way things went".
"I don't want to talk to anyone in the team," he added. "It will be all 'blah, blah, blah' and I don't want to hear that."
The Brazilian said team principal Ross Brawn had rung him in America at 6.30 in the morning on the Tuesday after the race to clear the air.
"He just said he really heard things that he hadn't wanted to hear but he also said that he had said things that he shouldn't have," said Barrichello.
"It was a nice conversation...and he just touched on the thing that, because I didn't have any personal problem, I should send an email to the whole team and I did with all my heart.
"I just said that I had no problems with the team, as I never had, I just had a frustrating race."
Barrichello has not won a race since 2004, when he was at Ferrari, and has had to watch while Button won six of the first seven races of this year.
Brawn have been beaten by Red Bull in the last two outings but hope to be back on winning form with new developments and helped by the Hungarian heat after two comparatively cold races that have favoured their rivals.
"We have a new update coming to this race and he [Brawn] wanted me to be perfectly straight to deliver my very best on this track," said Barrichello of the conversation with his boss.
"I'm definitely not putting any of the problems of the last race into this one."
