I have enjoyed using my phone as a quick way to check in with friends when life seems overwhelming or to encourage me in my day. I find if I send a text to a friend before doing something stressful, than I have more strength for the journey. If I have a rough day, or feel upset by something I can give a quick vent, and continue to address what I need to do. I have a few friends that are also my texting friends, where we check in with each other periodically. Texting is quick, can be done in a minute or two, and readily available.
As much as I love texting, it only works for me as a supplement for relationships that are already strong. The reason it works, is because it supports conversations we have already had, and a relationship that has been built by regular visits and conversations. It is meant for the positive, not for debates or conflicts – this is much better dealt with in person. It feels like twitter – where you give a few sentences reminding you of what is most important.
