How do you tell someone they're "lacking in hygiene"?

<p>"How do you tell someone they’re “lacking in hygiene”?
-You do not. Cannot change anybody by telling them. You ahve to exercise your veto power. Your veto power is to walk away. If anything/anybody bothers you, stay away. People are leaving their motherland if they cannot live there, staying away from couple people would be much easier by my estimates, but again you may choose to smell aroma. It is all about choices and our choices are ours, personal, what we choose, so basically we are in power to do whatever we want. “Smell or not to smell”, this is a question.</p>
