Your to passive.
If my partner started smoking in the ambulance (which he would never do) I would probably smack it out of his hand and made some degrading remarks about his level of intelligence for smoking in a vehicle with oxygen onboard.
If he was texting, I would Tell him if he wants to pursue natural selection as a means to remove himself from the gene pool, that's fine, but I didn't agree to it, and if he kills me I'll haunt him relentlessly.
There would be a few other more profane words thrown around in there as well.
Obviously if your new don't verbally assault your partner, but I have been with the same partner for a long enough time that this is the type of behavior we have succumbed to.
