A photo collection of Girls' Generation's "daily facial expression changes" has become a hot topic online.

The photo shows Girls' Generation and a related facial expression for the members, each day of the week. On Monday and Tuesday, the members look tired, but as the week moves on, they start to look a little more cheery. Friday and Saturday, they are smiling brightly. One thing that netizens noticed was that maknae Seohyun stays consistent, smiling throughout the entire week.

The collection definitely reflects the difference between what most people feel when the week starts and when the weekend begins.

Netizens who saw the post commented, "Girls' Generation's daily facial expression is hilarious," "I burst out laughing looking at Sooyoung," and "I think I am most similar to YoonA's expressions.  I completely agree."

What do you guys think?  Does your expression change depending on what day of the week it is?
