[EX Q]: [header] How to start a good conversation [title] Make the person feel like you care. [step] You can turn a total stranger into a friend just by making him feel like you care about what he has to say and that his opinion matters to you. If the person thinks you're talking just to hear your own voice, he'll be turned off immediately. <sep> (A) Make sure to be yourself as well--it's important that you show the person your worth. [title] Make sure you're a good listener. (B) Just making the person feel like you really care about him will make him forget his feelings and will also show him you don't care what other people think about him. [substeps] Make it known that you do care about him without ever saying so. (C) Instead, turn your body and focus toward that person and maintain eye contact without being too intense. Give the person enough personal space, but show that the person has your attention. (D) Keeping your voice soft and sincere will instantly make the person feel at ease and thus more willing to start a conversation. [substeps] Remember that just because someone has said something nice to you, it's a verbal invitation, not a direct action.

[EX Q]: [header] How to elevate your hand while sleeping [title] Sleep on your back or side. [step] In order to elevate your hand while you're sleeping, you'll need to sleep on your back or on the side opposite of the arm that needs elevation. This is the easiest resting position for elevating your hand. <sep> (A) [substeps] Lying on your side not only has been shown to help alleviate hand inflation, but it also improves circulation in and around the hand and wrist joints. It's also more efficient than sleeping on your side. (B) [substeps] You can use a pillow to support your arm when you start to feel like your hand's elevating off the ground. Place a rolled up towel over your head to help prevent air from pooling near your arm. (C) [substeps] Sleeping on your stomach won't allow you to elevate your hand as easily. It's much harder to prop it up from behind if you're lying flat on your stomach. (D) [substeps] Lie on your back with the pillow propping your head up at a 45 degree angle. Your dominant hand should support the bottom of your pillow.

[EX Q]: [header] How to clean a charcoal grill [title] Locate a suitable area to clean your grill. [step] This area should be away from your campsite or off to the side of your yard. You'll be brushing ash and encrusted char off the grill at this location, so it should be far from walking paths. <sep> (A) Also use a special charcoal-flame cleaner. [substeps] Depending on the type of grill you use, you may choose a specific area. (B) [substeps] Choosing a cleaning location far from walking paths will prevent ash and char from being tracked around your campsite or home. [title] Brush dirtiness from the grate. (C) [title] Fill the grill with the fuel you'd like to use. [step] This should come from either live wood or a frozen burned wood, both of which are avoided by wood hobbyists. (D) The charcoal is flammable, so it may strike inanimate objects in the smoke area. [title] Spray or spray the briquettes with salt water.
