It’s true relationships are all about communication. My pet peeve is about adult children and the Internet.
With internet and email things have changed, and not for the better in some cases. Yes, we have social media but most people want to 'hear' their children’s voice not read their conversation no matter what age their children are. There is no question phone is better than email, and if possible in-person is better than the phone.
Even if it's just a short phone call or visit, it is welcomed and enjoyed much more. When differences arise both parties need to respect the other. Each is entitled to an opinion, however if the opinion is hurtful, it is often better left unsaid. And it's always easy to agree to disagree before a conversation becomes heated. And that's OK.
