Unsticking grass from lawn mower blades

Dear Heloise: I spray cooking oil on my lawn mower blades to keep grass from sticking to them. I don't use motor oil since it can kill my grass if it drips on the lawn. Dan W.,in TennesseeDear Heloise: For those who serve hot dogs and those who like to eat them, I would suggest the following:Place the preferred condiments in the bun before adding the hot dog. This way, no more condiments fall out, and your hands don't get messy. I enjoy my hot dogs much more when my hands don't smell like mustard and onion. Dorothy M.,in Canton, Ohio Dear Heloise: I have a fat cat and a skinny cat. I separate them at mealtimes so that they can't see each other. But I have an open kitchen, and there's only one out-of-the-way place to feed them. So, I went to a craft store and got a slab of foam and a couple of foam blocks. With glue and duct tape, I created a barrier that I can put between the cats' dishes so that the skinny one doesn't feel intimidated by the fat one.It's simple to remove and store out of sight when mealtime is over. Now I'm looking forward to having both cats at the proper weight. Arlene,in Anaheim, California Dear Heloise: Please tell your readers to leave their young children with a friend, relative or professional sitter when they visit the doctor's office. First, the child can pick up a disease from another patient. Second, the nurses cannot and will not babysit your child. We have too much work to do.If someone needs to drive you to the physician's office, be sure that it's only one person. Sometimes the waiting room gets filled up with patients' relatives, and there is little room left for those who are sick. A Nursein Illinois Dear Heloise: I discovered that if I have something that's still serviceable and still of value, such as an old dishwasher or dryer, I can put it out at the curb with a sign stating: "It still works, and it's yours for free." By morning of the next day, it's gone! Latrice W.,Koontz Lake, Indiana Dear Heloise: There is a new scam in town: infusing plasma from a young person's blood into an older person as a way to treat Alzheimer's disease, memory loss, and almost anything related to aging. It's about as effective as snake oil. Since the Food and Drug Administration has warned the public about this scam, there are fewer companies trying to push this bogus treatment, but some still persist. Do not fall for this scam.
