Looking for my dad
We have never really heard of anyone who texts random numbers in an attempt to find their father. We are sorry to hear that this father abandoned them at a young age, but there must be a better way to do this. Nevertheless, they are out there, texting strangers in search of answers.
Just how many people a day does this person message randomly, immediately accusing them of leaving them at a young age? Perhaps there is a better opener they could start with, possibly a normal greeting. This might raise the chance of them having better conversations with people who might be willing to help them search for their father.
