Final answer:
Without context or access to the narrative or event in question, it is impossible to accurately answer who David texted before his phone died.
Step-by-step explanation:
The question 'Who did David text before his phone died? (he forgot his charger)' does not provide enough information for me to determine who David texted before his phone died. This seems to be a question about specific details from a narrative or a personal situation, and without additional context or access to the story or event, I cannot provide an accurate answer. To help David remember who he texted, he may want to check his phone's message history once it's charged or ask friends and acquaintances if they received a message from him before his phone's battery ran out.
