I cover my head full time. I do it because I want to follow the Holy Theotokos example, because of Corinthians, the angels, and because we are called to pray without ceasing.
I don't wear make-up to church because I don't want to kiss an icon or the priest's hand and leave a mark
But for work I wear a bit of lip gloss so I don't look so pale. I also prefer to wear skirts to church, but to work I also wear trousers and modest shirts.
It is a challenge sometimes because as any woman, I sometimes feel like I want to show off my long hair, sometimes the scarf bothers me, or people at my workplace bully me. They have called me many names and have reffered to me as raghead....but you know what? It keeps me grounded! If Jesus went through so much humiliation from the people He gave His life for, I can put up with being humiliated by people I don't care much about.
I don't think the scarf makes me hollier or even pius, I just think it is like a living prayer. Talking the talk is easy, but wearig a head covering makes my walk harder than it coult be, therefore it humbles my horrible pride.
