seeds for creative excuses

i guess that one of the triggers for creativity in an individual is when one has to come up with excuses.
not sure if excuses are created to get rid of one's guilt feeling or to escape additional comments from others.
in any case, i find that such situtations provide a lot of scope for creative excuses.
after some time, these could become expectations from others - like in my case, the excuses for not having green tea, have become expectations.
i am forced to come up with reasons why that is not the right time to have tea.
these excuses are not considered valid and i anyway end up drinking the green tea.
not that i do not like it - in fact, i like some of the flavors - it is just that i prefer if it is more like iced tea - chilled.
