So I think you never received them. The last message that shows up from me above is "Oh Amway I do not think I am wasting time... I have an intuition I found him. Do you know what intuition means? " but I wrote other things later. Definitely, FB is not always reliable!!
So I will repeat what I wrote yesterday...
During my flight yesterday, after making the phone call, I thought about the situation again. I concluded that we cannot give up now. I found too many clues that it might be him. There is some information I found online about him that makes me think that. Also the way the phone call happened... it was a strange feeling... there was something this person was hiding and not willing to help, very much on the defensive. The way the response was worded... it did not say directly it was not him, and it did not say it was him but that he did not want to meet his family. It was very vague and wanted to avoid giving details... something to hide.
My conclusion is that this is too important to stop now. We cannot just assume that Arnold does not want to help. Why? Because I have not talked to him directly. We need 100% confirmation straight from him that he is not the person we are looking for, or that he is, but that he does not want to go back to the past and contact his family. We cannot rely on the person I talked to on the phone. This person told me that he asked Arnold to talk to me and he could not help. But is that true? Maybe not. We cannot give up and necessarily think this is what happened. One of the hints is that I believe this man recently moved from the state of Connecticut to the state of New Mexico, and he lives with a woman (71 years old) who has a different last name than him so they are not married. This is a bit unusual in the USA for this age to live with someone not married. Because he moved recently, it is possible he has met this woman recently, and that this woman does not want Arnold to contact his old family. Maybe it's her who is blocking my phone call, not Arnold.
The other thought I had: we have to think of the situation Arnold is in, assuming it's your grandfather. It's been more than 40 years, then suddenly someone calls his house looking for him. It might be quite a shock. He had to decide in 10 seconds whether to talk to me or not. Maybe he made a quick decision, but maybe he regrets his decision now? Maybe he did not sleep all night, thinking about the call. We do not know. If we send a letter in the mail, he has more time to think about the decision of contacting your family and refusing. It all happened very fast yesterday. Maybe he is scared. Maybe he does not know what to expect. Maybe he knows he has family in Thailand and he is afraid that your family just wants money. There are many questions he might have and we need to make him comfortable that your family does not have any bad intentions and he needs to know that your family would be happy to meet him, nobody is angry at him! Right now he does not know.
But for him to be comforted, we need to find a way to get all this information to him first. It just did not happen yesterday because I was blocked. Sending a letter in the mail would not be sufficient either, because I am afraid someone else who lives in that house might open it and throw it in the garbage can, if someone is trying to block the communication like what happened yesterday. We need to be sure it's Arnold who gets the letter and opens it.
