a) What kind of blanket has a zipper? I don’t think I have encountered any.
b) As the kind of person with several thousand unread emails, I don’t know why people bother? I can easily search for the important stuff, and visually scan the new pile a few times a day. I have better things to do with my life than manage my inbox, I don’t need that stress. Family, video games, basically anything else. It’s way more work than reward. I know a number of people this drives absolutely nuts, but I don’t get it.
