No Expiration

Proper manners are dying in current society.  People seem to think they don't matter anymore.  (Spoiler: THEY MATTER.)

Say please, thank you, and you're welcome.  People say all the time, "I just don't know how to handle a compliment."  I do.  Say thank you.  Also, if you feel awkward receiving compliments, you need to start giving them more.

Call before you drop in.  If you simply must stop by unannounced, keep the visit short, and don't gossip about how unprepared your victim was for unexpected company.  Spontaneity is cool, but don't confuse it with rudeness.

Treat your friends well, treat strangers as well as you treat your friends, and treat your family better than you treat your friends.  Family doesn't mean absence of boundaries.  Be on time, be awake, be interested, be informed, be polite, be engaged, be appropriately dressed.

Anxiety, depression, and trauma do not exempt you from basic rules of polite society.  Violation of basic rules of polite society catalyzed the anxiety, depression, and trauma in the first place, and a return to the basic rules of polite society will help facilitate restoration of your mental health.

Anything Jeremy Renner gets away with in the movies or on set doesn't matter.  Manners do.

Good manners haven't expired.  We need them now more than ever.  Good manners aren't a power play or a show of stuffiness, they're how you show people respect--for yourself as well as them.
