Is it normal to share drinks with friends?
Depends.It depends
Yes, plenty of friends share drinks, while others prefer not to. It mostly comes down to personal comfort and how careful you are about germs.
Sharing a sip or passing around a drink is pretty common among friends. Some people see it as no big deal; others would rather keep their cup to themselves, and neither reaction is strange.
If someone’s sick or has a cold sore, it’s kinder to skip the shared straw or glass. Otherwise, it’s just a matter of everyone being comfortable with it.
