A father was left completely speechless on his 90th birthday, as his estranged son who he had not seen for more than 25 years turned up to surprise him. Robert Thompson, 90, and his son Tom, 63, had not seen each other for more than a quarter of a century, following a falling out back in the 90s. For more than two decades the pair had no contact, but with a milestone birthday coming up and Robert's health in decline, his daughter Scarlet Charlwood and other son, also called Robert, decided to see if they could patch up old wounds. The pair reached out to Tom, and initially he planned to surprise his father during Scarlet's wedding in April – only for the coronavirus pandemic to put most of America on hold. Scarlet, 25 – who is Robert and Tom's half-sister – decided it would be best to aim for a later date - her father's 90th birthday, on July 26. With Scarlet and the younger Robert gathered in their father's home, in Fredericksburg, Virginia, in walked Tom, who had travelled from San Diego, California, with his family. Scarlet captured the moment on video, with Tom heading to his father to introduce himself. Robert let out a, "Tom!", in complete shock, sitting speechless in his chair as Tom introduced his father to his wife and kids, who Robert had never met.
