Should I tell my friend I don't like his beard?
What would make you put down your friend's looks like that?
Yes, because I want him to look his best
You run the risk of hurting your friend's feelings if you are not sensitive enough when telling them how you feel about their looks. Instead of being so negative, try to be supportive of their deicisons.
Nah I don't care about the feelings of others.
If you really are friends you should care about how he feels. Friends should be there to support each other regardless of styling choices.
