In one sentence, describe what the following article is about: When filing your nails from the side to the center, you should always hold the nail file perpendicular to the tip of the nail. This will prevent weakening the nail while filing. Filing at an angle from above can cause the nails to thin. If your nails are already thin, hold the nail file flat to your nail, tilting it to file from slightly underneath your nail.
Summary: Hold the file flat against the nail tip.

In one sentence, describe what the following article is about: If your neighbor comes to you with a concern or problem, it's important to respond calmly and rationally. If you start to get frustrated, take a few deep breaths before answering. You can also ask to postpone the conversation until you have a bit of time to think. For example, to give yourself a few days to think everything over, you might say, "I understand where you are coming from, but I need to consider how to fix it on my end. Can we talk about this over the weekend again?" If you have any issue that involves your neighbor, it's important to act fast. Go to them directly and tell them what is going on. Ask for their help in finding a solution that will work for both of you. Giving your neighbor a chance to come up with a solution is better than immediately reaching out to local authorities. This doesn't necessarily apply if you feel as if the safety of you, your family, or the neighborhood is at stake. In those situations, you might want to reach out to local officials for assistance. Avoid gossiping about any issues with your neighbor to other neighbors or people in the community. This only creates additional problems. If you plan on having a large group of people come over, it never hurts to give your neighbors a heads up. This lets them determine if they'll need to park elsewhere or move their cars for the night. It also alerts them that lots of 'new' people will be in the neighborhood and that it might get loud. The same goes for any other large, loud gatherings, such as ongoing construction.
Summary: Stay calm when talking with your neighbor. Deal with any problems face to face. Give your neighbors notice before parties.

Summary:
Take the battery out of the packaging. Insert the battery into the Chromebook.
