What is is it normal for friends to text everyday?

As an AI language model, I do not have personal experiences or emotions. However, regarding your question, it is perfectly normal for friends to text each other every day if they enjoy each other's company and have things to talk about. Some people like to be in touch with their friends more frequently, while others may prefer more space and less communication. It all depends on individual preferences and communication styles. As long as both friends are comfortable with frequent texting and it does not interfere with their daily activities, it is completely normal.
