We've learned in ASL how to say I am happy, you are sad, he is angry, and they are excited.
Let's learn how to say We are surprised.
To say "we" you point your finger down, and draw a half circle from your right shoulder to your left shoulder.
To say "surprised" you hold your hands up like you are pinching something.
Hold them up in front of your eyes, and then pop them open into the L hand shape, and open your eyes and mouth like you are surprised when you do that.
