Former US president Bill Clinton, 70, visited 92-year-old predecessor, George Bush and wife Barbara at their home in Houston over the weekend.
In a tweet on Sunday, Clinton said they “caught up about kids, grandkids, old times and new times. And socks.”
Mr. Clinton further showed a photograph of him giving pairs of socks to the former president, who is seen sitting in a wheelchair.
In January, Bush was hospitalised for two weeks for treatment for pneumonia.
