Narrative:

I was flying with a perceived 'weak' captain. I had been told by several other first officer's to 'watch' the individual. I was too busy wondering why he hadn't got the ATIS at our destination, that I didn't watch myself. I did not reset my altimeter passing down through FL180, nor did he call '29.62' (standard company call) passing the altitude, or reset his. I don't remember what he was doing when I leveled off at 9000 ft, (actually 8700) and then realized my mistake. I reset my altimeter and climbed up to 9000 ft. He did not even have an idea what had happened. ATC never said anything. In the future, when flying with an individual like that, I will try not to worry about what they have or have not done, and above all not get mad about it while the flight is progressing.

Narrative: I WAS FLYING WITH A PERCEIVED 'WEAK' CAPT. I HAD BEEN TOLD BY SEVERAL OTHER FO'S TO 'WATCH' THE INDIVIDUAL. I WAS TOO BUSY WONDERING WHY HE HADN'T GOT THE ATIS AT OUR DEST, THAT I DIDN'T WATCH MYSELF. I DID NOT RESET MY ALTIMETER PASSING DOWN THROUGH FL180, NOR DID HE CALL '29.62' (STANDARD COMPANY CALL) PASSING THE ALT, OR RESET HIS. I DON'T REMEMBER WHAT HE WAS DOING WHEN I LEVELED OFF AT 9000 FT, (ACTUALLY 8700) AND THEN REALIZED MY MISTAKE. I RESET MY ALTIMETER AND CLBED UP TO 9000 FT. HE DID NOT EVEN HAVE AN IDEA WHAT HAD HAPPENED. ATC NEVER SAID ANYTHING. IN THE FUTURE, WHEN FLYING WITH AN INDIVIDUAL LIKE THAT, I WILL TRY NOT TO WORRY ABOUT WHAT THEY HAVE OR HAVE NOT DONE, AND ABOVE ALL NOT GET MAD ABOUT IT WHILE THE FLT IS PROGRESSING.
