question:
[header] How to dry a dog [title] Allow the dog to air dry naturally. [step] This is the easiest and most enjoyable way for the dog to dry. After getting wet, the natural reaction of many dogs is to shake from side to side with great vigor to release the water. <sep> (A) Dry the dog by waving a towel near the dog and holding it in front of him as you shake. Dry dogs naturally shake after an accident, while dirty dogs are especially prone to shake from side to side. (B) This helps air to flow through the dog's body and speeds the drying process. [substeps] Letting your dog dry upside down with its chest out can help with this. (C) In less than 4 seconds of shaking, dogs can shake up to 70% of the water from their fur. [title] Stand back and allow the dog to shake the water from his or her fur. (D) To encourage this, your dog has to naturally dry themselves faster because you are taking a short nap before allowing him to dry itself. [substeps] Wait until after a shower or bath to air dry your dog.

question:
[header] How to paint watermelon nails [title] Remove any old nail polish. [step] Soak a cotton ball or pad with nail polish remover. Rub the soaked cotton ball over the old nail polish gently to remove the polish. <sep> (A) [substeps] Rinse away the polish from the peel and gently scrub away the residue, to avoid further staining the polish. You do not have to cover the peel in nail polish remover. (B) Don't wipe the wet cotton onto the watermelon, but rather gently rub it over the nail until the paint is lost. [substeps] Washing the cotton ball between uses will get rid of any old paint. (C) You can also wear gloves to avoid damaging your fingers. [substeps] The rubbing motion will help the polish to adhere to the nails. (D) [title] Paint your entire nail a light pink or red, the color of watermelons. [step] After applying a clear base coat apply a thin coat of pink or red polish starting at the base of the nail and working your way up.

question:
[header] How to cook broccolini [title] Choose bright green broccolini. [step] Fresh broccolini will also have fresh bases, firm stems, and tightly furled heads. [substeps] If the florets are beginning to turn yellow, the broccolini is no longer good. <sep> (A) Canned or dried broccolini should still be excellent, as they have a bright green stem and firm leaves. However, white broccolini can only have mild to moderate flavor. (B) The same applies if the bases appear dried out, if the stems have soft spots, or if there are signs of flowering on the heads. Broccolini should be stored in a tightly sealed plastic bag or container inside the refrigerator until ready to use. (C) If the broccolini is on its last layer of leaves, it is still good, but not yet ready to make some export steamed bread. Broccolini will have more mayonnaise than the finely milled kind, so you may think it's more appropriate to cook it instead. (D) Cook the broccolini in the refrigerator. The firm, bright blooms will take the broccolini out of the refrigerator once it is no longer fresh.
