    古代女子以黛画眉，故称黛眉。宋词中对于眉毛的描写非常多，《全宋词》中“眉”字出现的次数达到一千五百零九次。从审美学上来看，眉毛在人的面庞上的作用不容忽视，往往起到画龙点睛之作用。在一首诗词作品中，对于眉黛的描写，能体现女子的美貌动人。“层波潋滟远山横，一笑一倾城”（柳永《少年游》）描写了一个漂亮的歌女，眉毛像远山一样，眼波流转，千娇百媚。“远山眉黛长，细柳腰肢袅”（晏几道《生查子》）也是通过描写远山眉、细柳腰，向读者展示出了女子的美貌。

    宋人认为，眉毛是很好的表现情感的工具。通过对眉黛的描写，还可以表现委婉细腻的情感。宋代词人陈三聘在《鹧鸪天》中写道“春愁何事点眉山”，把女子画眉和春愁结合在了一起。同样用眉黛来表示愁情的，还有如“金缕歌中眉黛皱。多少闲愁，借与伤春瘦”（石孝友《蝶恋花》）以及“眉黛只供愁，羞见双鸳鸯字”（贺铸《忆仙姿》）。可以看出，宋词中关于眉的描写，很多时候都和“愁绪”这个意象联系在一起。眉黛代表女子，以眉而写愁绪，体现了古代女子的惆怅心理和孤苦命运。欧阳修的《诉衷情•眉意》中有这样的词句：“都缘自有离恨，故画作、远山长。”“远山”指的是北宋时期十分流行的一种眉形画法——“远山眉”，即眉毛细长而舒扬，颜色略淡。古人常以山水来表达离别之意，歌女画眉作“远山长”，表明了她内心的凄苦之情，因为她“自有离恨”，故而将眉毛画作远山之形。

    “花黄”也称“花子”“额黄”，是古代妇女面部的一种额饰。它用彩色光纸、绸罗、云母片、蝉翼、蜻蜓翅乃至鱼骨等为原料，染成金黄、霁红或翠绿等色，剪作花、鸟、鱼等形，粘贴于额头、酒靥、嘴角、鬓边等处。《木兰辞》中描写木兰得胜归家，换回女儿装的场景为“对镜贴花黄”，说明南北朝时期，在脸上贴装饰物，已然成为一种风尚。宋代上层妇女也继承前代遗风，在额上和两颊间贴金箔或彩纸剪成的“花子”。这种“花子”背面涂有产于辽水间的呵胶，用口呵嘘就能粘贴。晚唐词人温庭筠的《菩萨蛮》中描写道“小山重叠金明灭”，一说即指女子额前的装饰物有所脱落而造成的或明或暗的效果。这些装饰物，使得词人笔下的女子更添妩媚动人之态。

    “梅妆”也是宋代较为流行的一种贴面妆容，“梅妆”即“梅花妆”。这种妆扮相传始自南朝，宋武帝的寿阳公主在正月初七醉卧于含章殿下，一朵梅花落在她的额上粘住，三天后才落去，因而作“梅花妆”。陈允平的《绛都春》中有“梅妆欲试芳情懒，翠颦愁入眉弯”两句，这里词作者专门提到“梅妆欲试”，体现了这种妆扮在当时的流行性。妆容虽美，但是却“芳情懒”，欲画而未画，说明这位女子心事重重，自己提不起兴致也更因无人欣赏，故无须白白画这妆容，更能体现出女子内心的孤寂。

    What makes a gift special? Is it the price you see on the gift receipt? Or is it the look on the recipient's face when they receive it that determines the true value? What gift is worth the most?

    This Christmas I was debating what to give my father. My dad is a hard person to buy for because he never wants anything. I pulled out my phone to read a text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father. My eyes fell on a photo of a flower taken in Wyoming, and underneath a poem by William Blake. The flower, a lone dandelion standing against the bright blue sky, inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father.

    I called back. I told my mom to go without me and that I already created my gift. I sent the photo of the cream-colored flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind. The poem was written by Edgar Allan Poe; my dad recited it as much as he did the other. I typed that out as well and searched online for a background to the words of it. The poem was focused around dreaming, and after searching I found the perfect picture. The image was painted with blues and greens and purples, twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer, the white paper coloring with words that shaped my childhood, I felt that this was a gift that my father would truly appreciate.

    Christmas soon arrived. The minute I saw the look on my dad's face as he unwrapped those swirling black letters carefully placed in a cheap frame, I knew I had given the perfect gift.
