-Wink at someone: When you wink at someone, you show interest or attraction, and, of course, you also demonstrate positivity. For example, if you have a date and want to propose something fun, you wink to confirm it.

-Make eye contact: These reactions show interest between the people in the conversation. For example, in an interview, both people speak and listen attentively, and eye contact is a sign.

-Big hug: People give big hugs when they're being affectionate with someone or haven't seen each other in a long time. For example, when you run into your friend and the reaction is a hug.

-Thumbs up: People express opinions or feelings instantly when they want to react without speaking or with quick expressions. For example: your classmate is at the front of the class writing on the board and needs your opinion.

-Cross arms: When someone crosses their arms, it shows either interest or disappointment in the situation they're participating in, but it depends on the situation and the person. For example: When I pay attention in class, I concentrate better when I cross my arms.
