If my friend is sick, is it okay to take a sip after her.  I'm really thirsty.

It depends on how sick your friend is and whether or not you have already washed your hands. It's generally best to just ask your friend if it is ok if you take a sip. Be cautious and avoid taking any potential contaminants in the event that your friend may be vomiting. Additionally, make sure to stay up to date on your own sanitation measures to ensure good health for yourself and your friend.
