The little things you say matter- whether you choose to acknowledge it or not. The use of niceties in day to day conversation can make this whole wild ride seem a little less lonely and a little more lovely. Like we all understand a small thing about one another, we all speak a common language of politeness, of care, of willingness to take little steps out of the way in order to make someone else's paces a little easier.
Take pleasure in the niceties. Smile. Dot your I's and cross your T's. Please, thank you, bless you, good day.
