i don't care about having the last word unless i know the other person is the type who really wants it then i want it just to **** with them because i can be a petty child and it makes me happy to make them give up i had a leo friend i used to **** with like that all the time
if i know the person doesn't care then i'm fine with letting them have it once i've said what i needed to say
but if someone is going to argue with me and i have to deal with that long after it gets boring and they care then i want to aggravate them so i can at least "win" and feel satisfied about something
i have an aries moon trine leo mercury and sag uranus (opposite libra venus) square cap mars
edit: i also have uranus, neptune, and mars in my 3rd house in placidus sag on the cusp
