Just a light-hearted thing but a bit of a bugbear of mine...it (very mildly) annoys me that people now use the word 'partner' where we would have said boy/girlfriend back in the 90s. You see it on here - someone has been on five dates and now refers to their date as their 'partner.' Partner to me implies a serious, committed, long-term relationship including co-habitation - if not you're not really 'partnering' are you?
I get that girl/boyfriend might not seem that appropriate for people dating in their 30s or older - and might not cover all options for how people identify - but 'partner' still makes me go 'urgh!'
