I just want your opinion.
You ask teen to do something to help (a quick household task for instance) and they make a fuss over being asked, and in annoyance about being asked they throw your handbag on the floor outside that you asked them to hold (while you did task) and you almost drive off without it.
You are cross about this episode and state that was not helpful and uncalled for.
In response teen announces that they think you don't really love them anyway, why did you have kids, just get rid of them, and they have no idea why you are upset because they did indeed help you, as you asked and you are very OTT about the whole thing and 'dramatic'.
You lose the plot a little bit and realise you have ended up being the bad guy for getting upset and maybe you are too dramatic in defense of something that is not even true.
How do you deal with this better?
