Ouch. Sorry Inso.

The old "I'm treating you like a child because you're acting like one" crap that parents use when they run out of ideas.
You wouldn't believe the amount of that I've been getting lately, from my sisters (I can barely believe I'm getting it at all). 'Acting like a child' mostly consists of raising my voice an octave to get a word in edgeways, or having enough and just walking away, when they're in the middle of their rapid-fire criticisms (i.e. treating me like a child).
Teens not being able to buy basic modelling supplies. As I modelled since childhood I will start killing, no stopping me, if imagined future bans on the sale of paint and plastic fusing solvent to under 18s.
Not being allowed to kill.
To be frank, I'm all in favour of keeping hobby knives from you.

Something else that pisses me off: Noel Edmonds. I didn't get why people hated him the first time around; but when I'm slow with the remote and Deal or No Deal comes on the telly; and he launches into his saccharine hyperbole (e.g. "welcome to the dream factory"); and the vein in my forehead starts throbbing, I get it.
Lastly, not so much to do with anger as despair. I sat in on the local GW's greenstuff masterclass on Thursday. The redshirt giving it told the poor little newbies that contact with your hands dries greenstuff out, so they needed to regularly re-wet it. Cue a bunch of kids with amoeba-like 'cloaks', slick and slippery from a good dunk in the muddy paint water, trying in vain to push them on and make them stick to their little SMs and IG.
Oh, and showing off a certain Professor and being asked 'What army is it for?'
