Who else is too lazy to pump up the bicycle tires?

Usually ride on soft tires. Inflate only when rim permanently touches the ground or when I have a long way to go. Occasionally I´m told to pump it up by other people, they probably think I don´t realize the bulgy tires. Some comments are not very polite. But I don´t like fully pressured tires, I want them soft. So I inflate only enough that they are almost but not completely flat when I sit on the bicycle.
