Margaret's mother reveals that she keeps a "son-in-law" file on her computer. When she loads it up, she points out "This one only goes from A to Park. I keep telling your father to free up more memory!" This makes little sense for two reasons. First, memory is not where files are stored; they are stored on the hard drive's disk space. Second, if she has two files split by alphabet, then there isn't a storage space issue, she has just split the file for no good reason.
