Just that really? I would have bet money that after his latest disappearance he would spontaneously appear today, and lo and behold, there was a missed call. He doesn't live in this country so he can't just show up luckily. He just wants some recognition and to feel good about himself but if you were (or have been) in a similar position would you message something about why you're not answering the phone or just ignore it completely. DD is only just two and knows nothing of his existence.
