Why does it seem like I never hit the flop?

Ok, NEVER is a very strong word. But I'll play fairly long sessions where I maybe hit the flop 4-5 times. I had a game like that the other night, in fact. The same one where I had 0 pp in about 100 hands I also only had top pair on the flop twice.

This isn't an uncommon thing for me, either online or in most of the games I play. And sometimes it can be quite frustrating when playing a soft game, not getting ANYTHING with which to punish the fish. It does sometimes put me on tilt. (I end up playing MORE hands, missing the flop MORE often, tilting even worse. One of my 'tilt signals' is that I start playing hands like T9o aggressively from EP or MP.)

What I'm wondering is how much of what I've explained more my own perception than reality? Or is this somewhat accurate and if so is it the reality for most other players?
