Percentages. It's all about percentages.

Number of roaches in my house in five years: maybe 20
Number on me in the bed: 5
Percentage of spotted roaches on me in my bed: 1/4 of all roaches

Number of students in my son's class: 23 (hopefully down to 20 by week's end)
Number of bullies from our neighborhood who made it into the class despite the fact that there are six kindergarten classes at school: 1
Percentage of evil for my son: 2/138 or so, or 1/21, given that there is at least one more freakish bully type in the kindergarten.

Number of credit cards my husband and I hold: 6
Number lost by us in the last month: 2
Percentage of ineptitude in this house: 1/3 inept


There's more, but I need to go spray insecticide and maybe gargle with it.
