My passive call down of the day

Am I a fish for doing this? I figured that all I needed to take the lead was any ace or king, and any flushes that landed in my lap were welcome as well. I now realize that a push would have had to fold him out, but I really didnt feel like racing. His bets were so weak they were just begging me for a huge raise but I wussed out. I guess I've been letting my bad run affect my play in instances like this.

Nice job... Fish!!

Well I was a favorite on the flop...but I didn't want the variance of a slightly +ev push so I figured I could just call down and see a cheap A,K or club. Just so happened that my club made his straight
