One part of my life that I regret the most is somehow losing all of my family photos when moving house. I only have one photo left from my childhood which was taken while on a school trip. It makes me sad to think that this is the only photo I can look at as a reminder of the past. I don't know what happened to all the family photos but I remember where they were kept just before the move.
Losing these photos has meant that I have lost all of my family pictures and I'll never get those back.
