Very important thing to find out if you're living in a college dorm.
THE SIZE OF THE MATTRESS.
Because most colleges use extra long twin size mattresses which standar twin size sheets will
NOT fit. Thankfully most stores like Walmart, Target, Bed Bath & Beyond now sell extra long twin size sheet sets for roughly the price of normal twin size sheet sets. Oh and a vinyl cover for the mattress... you really don't know who did what on that mattress the semester before you.

Then cover the vinyl cover with another mattress cover made of cloth... off hand I can't recall the correct name for that but it's like a pad... oh duh, mattress pad. Then your sheet and get those sheet clips to keep the sheets from sliding off. They remind me of mini suspenders and are like $3 at Walmart.
Actually, most online sites have lists of what you might need to take to college but keep in mind most of those places are aiming to sell you those things.
One thing you might want to invest in is a shower caddy to take your shampoo/conditioner, lotions, soaps, shaving cream, razors, etc. Many stores sell bathroom stuff (mirrors, soap holders, shower caddies, etc) that have suction cups which I highly recommend since you don't want to put your stuff down on a floor where who knows stepped on.
Another thing to invest in is a small cleaning kit. Seriously, public bathrooms are... EWW. College bathrooms are worse since janitors typically do not clean out those bathrooms since it falls to the responsiblity of the people living there. Again, EWW. So gloves, spray bleach, bathroom spray and disposable toilet bowl brushes are a must in my book. Then again, I can't use the toilet after my hubby without first cleaning it. EWW. EWW. EWW.
Some links for those "college checklists" (just keep in mind most of that stuff you won't use/need/or be allowed - like some colleges/university dorms prohibit microwaves/mini fridges/toaster ovens).

Oh and incidently on the locked box. I recommend, to another person a few years back after a roommate problem occured, was to buy a cheap cabinet from Walmart/Target/ShopKo for about $15 to $50 (depending on the size) then go to Lowes/Home Depot and buy a lockable hasp (about $5). Keep food items, toiletries and cleaning supplies locked up because you might find your roommate "borrowing" stuff without permission. That person in question was buying food only for the roommate to take it without asking or repaying her.
How the hell do you play with a goldfish?
Actually, goldfish are pretty playful for fish. Mine, which are now five to nearly ten inches in length, are pretty playful. They follow your finger, come up to be petted or nibble on your finger. Except they're pretty stupid when it comes to our cats because they think the cats want to "play" with them. Stupid fish, they want to EAT you, not PLAY with you.
