Chem group working with at equilibrium project when, 

"Put your attitude away...it doesn't even match your outfit!" 

"OMG! You are so RUDE!" 

Laughing from both sides

Laughing from all sides

Saying silently: "We know this is for humor" 

Saying silently: "we know each other well" 

Silently saying: "You are funny, and sweet, not rude."

Silently saying: "We can do this because we know each other's personality" 

Each other saying: "We are the friends who can trust each other with our hearts."

According to Le Chatelier: There is always balance required when the scale tips one way

Things that seem calm are always active underneath
