Meeting her parents for the first time !

Hi guys ! I need your help. I am a non-Odia and I am going to meet my long time girlfriends’ parents for the first time tomorrow. They are traditional Odia parents. Although my girlfriend says they are chill and all, still I want to know how to deliver a good impression on them.

Please do share your insights as I want it to be smooth and easy.

Also, I have planned to gift them a picture frame of Mahaprabhu Jagannath, Subhadra ji and Baldev ji. Will it be a good gift ?
