Let me fill myself up. For example, even though he's not hungry at all, he may head for the refrigerator and just stand there with the refrigerator door open, trying to decide what will satisfy him. Actually, such person is like a walking, talking vacuum cleaner, sucking everything. Or like an octopus, reaching out with his tentacles and sensory suckers, trying to drag in anything and anyone he can. For example, some people will sit in front of the television with a bowl of food, a drink on the table, a smoldering cigarette on stand-by in the ashtray, the radio and a newspaper in their lap, trying through each of their sense to get as much as they can.
Smoking has no value.
You suck in the smoke and try to hold it as long as you can. But because you breathe it in, you've got to breathe it out. So you blow it back out. You're not getting anywhere. You take it in and blow it out, take it in and blow it out.
