Thanksgiving is one of the few holidays we don't have in Thailand. I never understood the significance of this holiday, other than the two-day school break, until I traveled on Thanksgiving Eve, this past holiday. A taxi driver who accompanied me to the airport mentioned its importance by saying that “Tonight is one of the busiest travel times of the year.” I didn't fully understand his statement until I saw how crowded the airport was. I felt like everyone was going home to celebrate Thanksgiving with their family. However, what was funniest that night was the scene of dozens or even hundreds of people waiting for their family members at the arrival gate. I wasn't clear on why there were so many people, so I decided to do an ethnography on these people to help me understand the reasons behind their actions. The social behavior I have observed specifically is the phenomenon of a huge amount of people gathering and waiting at the airport stop on Thanksgiving Eve compared to an average day. While some may question the importance of this phenomenon since airports always seem busy, they may not have considered other constraints associated with Thanksgiving Eve, such as traffic jams and large crowds. Possible explanations for this phenomenon are due to pressure from the parents' neighbors, or to an economic reason such that it might be faster for parents to pick up their children that night instead of using public transport. To answer this question I used ethnography instead of quantitative analyzes or experiments for several reasons. First, variables for quantitative analysis must have numbers; without numbers we cannot use any statistical technique. The possible quantitative variables for the question are... at the heart of the article... and really make sense of the phenomenon. In summary, by performing an ethnographic study of those who waited at the airport on Thanksgiving Eve, I found that these people, despite the traffic and crowds on Thanksgiving Eve, still come to the airport out of a desire to demonstrate their love. to the arriving person. In terms of generalization, while we can generalize our results to different airports on the same night, we cannot generalize them to all airport waiting situations, such as when parents come to pick up their children on other days because the situation is different due of traffic and crowds. Therefore, our discovery is bounded by a specific time period. Finally, this study indicates that the best moment of Thanksgiving is not a big fancy dinner on Thursday, but the first time we gather at the airport on Thanksgiving Eve..
