Badly designed stuff (eg a bank cheque deposit slip which has a large space for the paise column, and very little space for the rupees.)
Packing for a long journey, and a long stay away, with the present weight and security issues.
The prospect of a long journey ahead of me, and the worry that I will forget to pack several important things.
The fact that I still don't have proper control over my temper or tongue.
The fact that I am not as good a person as I should be. Where is the grandmotherly serenity and maturity and wisdom?
