Just remember, you can't deny anything that you put down in print.

That's a good point, Lucy. That's why you need to take time to read check what you write again and again before sending it to the one you are upset with. Doing so, there is chance you will change your mind and not send the letter.

I am good neither in speaking nor in writing LOL. Though, if I had something to communicate with my spouse, I would prefer to talk to her to make sure that I am not misunderstood.

I think it really depends on your character. If you tend to get carried away with what you are saying and do not think before you say it, particularly in an argument, a text message may be better but it is a lot less personal and maybe even serious. Sometimes just talking about it can clear a lot of misunderstandings.

I don't think you should text either.  I mean just don't talk to them until you are ready to talk sensibly.  I like Natasha's answer about taking the message the wrong way!

I love text messaging when I am angry. Especially when I am trying to communicate with my spouse. He is pig headed sometimes and doesn't listen. He usually gets what I am saying when I text it. He reads it and lets it sink in.

When you are upset with someone, it's better to communicate your strong feelings to him/her through text messages instead of a phone call. Sending text messages, you will have more time to think about what you will tell the person and keep yourself from getting the situation worse. At least that's what my friend told me. What do you think?
