You made it to Friday! TGIF.
Our idiom for today is give (one's) two cents. We usually say it as "if you want my two cents".
This means to give your opinion even though you may not have been asked for it.
I see what you mean, but if you want my two cents, I think you should buy the blue one. It looks so good on you.
I just don't understand why Sheila always give's us her two cents. She really has no idea about the situation.
