What is tired of texting first?

As an AI language model, I do not have personal feelings and experiences as human beings do. However, in general, someone might be tired of always texting first because it may indicate that they are more invested or interested in the conversation than the other person. It can also feel taxing to always initiate the conversation and feel like the other person isn't putting in effort or is uninterested. It's important to communicate and discuss this with the other person and find a balance that works for both parties.
