I often test others.
I want to know wheter they keep staying around me.

Many people take the test and fail it. (they are normal)
Some people don't take the test and leave. (they are wise)
Several people take the test and pass it. (they will fail eventually)
Few people don't take the test and stay. (i want to trust them)
My husband sometimes doesn't notice the test. (he is unsensitive)
When he takes the test, he always fails it. (he doesn't understand me)
And he stays. (maybe he is somehow special)
