Living with other people* has taught me so much in 21 years:
#1. Don't worry or be afraid.
#2. Talking honestly and a lot is important! Consider the affect your words have on others.
#3. Laugh, dream.
#4. Be gentle and patient with animate and inanimate objects.
#5. Be a lady.
#6. Work hard and be disciplined.
#7. People will talk differently, do things differently and like different things than you and that's OK.
#8. You can't make anybody do anything, you have to respect everyone.
#9. People have different perspectives that will surprise you and help immensely in life.
#10. God is love and His greatest expectation of us is love. Love is patience, kindness, forgiveness, mercy, trust, protection.
There's so much more but this is the tidy, 10.
*I live in an "intentional" Christian community. We live on about 120 acres of beautiful country in mobile homes. Though it is now one family per house on average, growing up I have lived in houses with one or more families plus grandparents and single people in the mix at times. Our number one belief is that God wants us to be a gracious and kind family seeking Him in everything.
