It's seems to be often used by scientists, economists etc or other experts in their field sparkle - and hadn't realised it had become quite so widespread. I think on the media those using it try to sound authoritative ie "I've done a lot of background work and reading to enable me to answer this question and therefore you need to take notice of what I say". I'm not knocking all those people who are give their opinion but the "so.." bit does sound daft!
One of my pet hates is "Awwwwwww" - that is the frst and last time I will ever write it! It is only ever written and I'm not sure what it's supposed to mean. It's never said, is it, and seems to be a product of social media maybe? I mean when you see a cute creature or fluffy animal you would say "aaah". If you're feeling sympathetic towards someone you would sympathise or maybe say "there, there" (well I still do to my children!). I don't know where it comes from but I absoutely hate it! Not sure why it evokes such a strong reaction

Wrapping paper - good on your mum CLKD - not sure about the ironing though? I've always kept the big bits of wrapping paper and cut them into squares ready for all the stocking presents for next year. Also make gift tags out of old cards. It does save a small amount of resources....
