I was grocery shopping and a guy approached me and we chatted. before he left he asked me to take his number. We texted but he kinda disappeared?

Why would a guy not communicate if he approached me and said he wanted to connect? Please see screen shot

Oh no I wouldn’t ever ask someone what to say or to analyze anything deeper than what’s already posted. Your answers have been all of the help that I need. I really appreciate you.
