Tui agents Debbie Palmer and Julie Anderson's more than 40-year friendship has only threatened to fall apart once.
The pair are two of Tui's longest-serving and most prolific sellers, with their sales skills earning them more than 15 Tui awards.
However, in 2011, Palmer left the job she shared with Anderson at Tui's Waltham Cross store to rescue an underperforming branch 15 miles down the road.
Anderson, the more organised half of the self-proclaimed Terrible Twos, reveals how she initially struggled not having Palmer by her side every day.
