Souvenirs?

I seriously do not understand people who collect the Starbucks City Mug Collection by asking other people who go on trips to buy it for them. I mean, isn't this supposed to be your souvenir from the place you visited?

 Well, for me anyway, I personally collect these mugs every time I go out of the country. So far I only have 3 (Singapore, Washington DC, New York). But I already promised myself that this would be my only souvenir collection for future trips outside the country. No way I would ask any of my friends to buy it for me. I mean, anong point?

But anyway, as my sister said, "kanya kanyang trip".
