I'm going to make my partner wait for me to have a cigarette
Why are you smoking cigarettes?
Because I'm addicted to it and I don't have enough willpower to quit.
I see what you are trying to do here, but smoking is bad for you, and for others, you should try quitting it. If you don't, you might die young from lung cancer. You should try asking your partner to help you to quit.
I don't care about cancer.
You should care about cancer, don't you want to live for as long as possible?
