MrsR and Coffee- everyone needs vintage Miss Dior in their lives. I think I now have 4 generations of it. A good thing about it though, is actually, the modern version is still immediately recognisable and just as wonderful and demanding of its wearer. It's definitely a "you don't get to fuck with me, missy" perfume. I wear it for the headmistress. 
Coffee- if Diors have passed you by, pull right over and turn round, everyone needs the Holy Trinity (Miss Dior, Diorella, Dioressence- I am totally unable to decide which I love the most, Dioressence probably wins it by a whisker) (Diorling and Diorama worth a punt as well, as of course is Diorissimo. But that's very feminine. But not in a pink minger way, just very very white flower- almost a soliflore lily of the valley to my untrained nose) If you're going past a counter, you'll need to ask them to fettle under it probably, and wait patiently while they shift the eleventy billion flankers of new Miss Dior (ignore everything with a velvet bow) Ebay is your best bet- especially ebay.de. Lots of 10ml bottles. (I do think, because they're splash bottles, some have been naughtily topped up, but you do get some treasures)
Pineapple- dd and I are almost as obsessed with home scent as we are with human scents I even like Yankee Candles. 
The most wonderful candle ever though is the Liz Earle special Rosemary and Eucalyptus one. I got one free with a skincare set at Christmas and dd and I fought over it. It made me realise the difference between £ candles, and ££££s candles. I dabbled a lot in essential oil blends years ago, and a favourite blend was lavender, geranium and neroli. Re: Yankee- melts all the way. They fill the whole house, whereas I find the candles won't go further than a radius of about 6 ft.
The most wonderful room spray is L'occitane Relaxing Pillow Mist- I use it all over. Mine is almost finished. I treat myself to one every summer when I head off to summer school and dormitory living for 6 weeks!
Fennel- I hear you on the academic year. I am actually sick today (throbbing migraine and threw up at 4, now feel fine and fraudulent obvs) And I was taking 34 students for exams. Tomorrow (Sunday!!!!) I am taking another 76 and then the exams for me are finished. Just 4 weeks of lessons and paperwork, then summer school, which is physically draining but a mental doddle.
If anyone needs to be enabled, I enabled myself with 100ml of Eau d'Hadrien from a German ebayer who seems to be getting rid of a lot of AGs. Auction and BIN. It's become my "can't stop sniffing my arm" scent this week.
Postie bought another ebay accident. A third of a bottle of vintage Obsession. I was sceptical as I thought yeah, everyone sticks vintage on it and doubles the price, but as soon as I smelled it, I realised how much the monstrosity on sale now, masquerading as it, has been defiled. Just No Comparison. When dp comes home I shall make him smell it as I was wearing it when we met, and have rarely worn it (due to modern monstrosity prevalence) since.
Fingers crossed for Mr Judy.
I am also attempting to not buy. Hmmm. So I joined the skincare and how to look expensive threads. That's going to work then.
