Many viral posts and movies have depicted friends and family members who shave their heads to support someone with cancer who is losing their hair from chemo. While it is a grand gesture that is appreciated by some patients, it's not appreciated by all. Many people attach a part of their identity to their hair and losing it for solidarity might not be the best way to support their loved one, especially if there was never a conversation about whether or not the patient would appreciate it.
Plus, there's always the question of where to draw the line. You might not even think twice about shaving your head for your sister or your best friend if that's what they want, but should you feel obligated to make a major change in your appearance for an acquaintance? A neighbor? Your co-worker? That is the exact question that a recent reddit user asked in the "Am I an As*hole?" section AKA the moral compass of the internet.
