Hmm, things I've done in the past few weeks:
-after taking some, put the (delicious and new) ice cream away in the fridge and didn't notice until the next day when it was melted and completely ruined.

-making KD (mac n cheese for you americans), wasn't thinking and after pouring the noodles into boiling water, opened the cheese packet and poured it in. Yes, I know how to make it properly and have made it all too many times before. Yes, it makes a horrible mess and ruins everything. Yes, I have actually done this before.
-forgot my glasses at home today, making it extremely difficult to do computer work (which I have to do today). I bring them every day so it should be a routine by now.
And of course the things that I'm used to since I've done them my whole life
-losing important things like my work badge I need to get into work (yesterday and still lost)
-misplacing groceries, random things everywhere
-forgetting the laundry in the washer or dryer forever (well a few days)
-washing lots of important things or money after forgetting to check my pockets
-bashing into things as I walk around, so much that I can't remember ever not having bruises all over my shins, knees and sometimes elswhere.
-constantly losing umbrellas. I've kept this one longer than usually purely because I keep leaving it on the bus and nice people shout after me (probably 75% of the times I take it anywhere on the bus).
-many more unfortunately
