The present paper elaborates on the usage of perfective -teiru in daily conversation. As it shows that the influence of the past event still remains, we can convey this aspect to the listener by the manner in which we use -teiru. For example, if a speaker describes the listener's matter using the perfective -teiru and his/her own matter with only the past tense, then it means that the event is still occurring from the listener's perspective and has been completed in the speaker's perspective. On the contrary, if a speaker wants to argue his own matter, he might describe his own events using this -teiru to avoid it being considered as something that has passed.
