In this comic scene from 'Just Kidding' series, directed by Mehran Modiri, you can see how expectations for good souvenirs pan out.
In Iran, when the uncle comes back home from a long trip abroad, his niblings may expect good and memorable souvenirs. Though in this sequence from 'Just Kidding', the uncle is less likely to be well remembered by his nieces and nephews for obvious reasons.
By the way, do you think a souvenir should be pricey or just like in the series, the thought is important?!
Looking forwards to hearing your thoughts on this and you can definitely share some of your culture-bound experiences regarding souvenirs.
