Example Input: [header] How to prepare your skin for waxing [title] Let your hair grow. [step] Don't book a waxing appointment until you haven't waxed for least one to two weeks. Ideally, you should have 1/4 inch (. 635 cm) of hair in the area you want to wax. <sep> (A) Additionally, waxing will help repair damaged skin and nourish the skin. Let a few days or no more than a couple weeks pass between waxing times to allow for new growth. (B) Don't wait until your hair has grown beyond this length unless you absolutely have to.

Example Input: [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.
