Is it normal to kiss people?
Depends.It depends
Kissing is a normal way to show affection or greet someone, but it depends on the situation and what the other person is comfortable with. Make sure they want it too—being close to someone doesn’t automatically mean they want a kiss.
Yes, people kiss for all sorts of reasons: romance, affection, or even as a greeting in some families and cultures. How common it is depends a lot on your social circle and where you are.
The important part is consent. A wanted kiss can be sweet; an unexpected one can feel uncomfortable, so it’s fine to ask or wait for a clear signal. And you’re allowed not to want kisses, even from someone you like.
