One of my current lecturers looks like Richard will in 25 years time, and I have to constantly fight the urge to hug him. It's not that I have a crush on him or anything like that (thank $deity that I'm mostly too old for that sort of thing except when it comes to synthpop bands), just that he's so fluffy and beardy and geeky and jumper-wearing and softly-spoken and tea-drinking that I feel like I already know him much better than I actually do. He is always smiling and very enthusiastic about what he teaches, to the point where I find myself wanting to nod and agree with all of it simply because he's so nice.
Must remind self. Hug family wuzzies because they're mine. Do not traumatise lecturer wuzzies by trying to hug them. That would be cruelty to wuzzies.
