3 quick KT hands - too passive?

[cs3]

<font color="blue"> im normally really aggro with anything close to top pair, but i have been trying to slow down some lately to avoid the patented cs3 stack-a-self line.
just a few quick hands i played passively... please give me your intial reaction to how these were played.
