It is a lot more fun doing errands with a friend than alone. Granted, this is difficult, but perhaps once a year you can go to a bed and breakfast, or rent a beach house, for a few days. The getaway doesn't have to be expensive or elaborate to renew your friendship. You may want to include husbands and children if everyone gets along well. If the answer is watching television, then one night a week, forsake the television and instead meet your friend for a quick cup of coffee.
Friendship is work.
Like all relationships, it demands something of us. If we value our friends, we won't be resent the need to put aside time for them.
