Chimdinma thank you for completing the work. I realise that this was a new exercise for you and perhaps not intuitive therefore taking longer than someone who has the experience. You achieved the goal, well done.
Some feedback on your communication style - you can be very direct which sometimes comes over as aggressive. May I suggest when you are discussing financial issues that you remain direct, but open a discussion rather than making a statement of what you want so as not to damage the relationship.
Hope this is helpful going forward.
