I actually love life itself...it is possible especially after you have had a brush with death. For me the most irritating thing is where people say "Oarsome" rather than "Awesome". What has rowing got to do with it????
I think you are all being oversensitive. None of the phrases above bug me at all.
I do not like to hear people say "I swear on my life.". What if they had a death wish on themselves, what good would it be then? They would not really die if they were lying, would they?
