New Year's Day:
I had just finished a load of dark coloured laundry and was putting another load in the washer, but of lighter colours. I didn't have anywhere close to a full load, so I added a couple of white shirts that didn't require bleach... There still wasn't a full load, so I went looking for something else to add and all I could find was a black fleece robe and a fleece-lined shirt, both of which should have been washed in the "gentle" cycle separately with dark colours.
I did it all together anyways... on "normal" cycle... with "regular" laundry detergent.
