Atheists, do you sometimes 'pretend' to be religious?

i sooo do. especially when there's religious occasions at church or festivals. its like i miss those days when i did believe in god. but the funny thing is, i can totally pull it off. i can completely hold the bible and sing hymns and choirs, say the quotes etc. my family doesnt notice a thing. i miss the age of innocence i guess... truth hurts. but it strengthens my community spirit.
