Many of my relatives in Lahore had Sikhs visit them to see their old homes and havelis. They even had lunch or dinner with them before setting back to India.
People to people contacts in Pakistan has lessened a lot of bad blood over the years. Pakistanis have big hearts to forgive and overlook these things.
Many people nowadays have positive opinions of the British and Sikhs, regardless of what they may have done to us in the past. Visitors are always treated with hospitality and kindness, and this is our biggest khoobi.
