Generation Gap (Just a small 8 years.....)

Today was Marcelo's 5th birthday, and my sister's and I were invited. The night before the kids prepared a bag of presents for this boy that they barely even knew. This bag of presents included: A writing of the word "President" on it and some drawing, which was probably influenced by my dad because he just took the citizenship test yesterday and he has been studying in front of the kids for the past week. More drawings of birthday cakes and of course the words of "Happy Birthday Marcelo" on it. A turkey card from Thanksgiving that the kids made from school. A coloring page ripped out of a coloring book. Pages with stickers stuck on them. And last but not least, a paper towel ROLL with stickers on it (just the roll guys, not the paper :/ ).
Okay, first thing that came to my mind was that "this is .... trash." and I was really embarrassed about that paper roll! What was it anyway...? ITS SOMETHING THAT BELONGS IN THE TRASH! And the word "President"? How is that relevant? I wanted to tell my sister, Hannah, to throw it away because I really didn't want to see the birthday boys expression when he finds this bag of presents among the other boxes of trucks and iron man and nerf guns and whatnot. I was embarrassed.... But I didn't want to ruin my sisters' childhood (cause honestly I blame myself for them being so crappy at times :/ ) and decided to let her have her way. This is where art starts right? Like the book "The Little Prince" I don't want to be the reason why my sister is kidnapped from her creativity...
Skipping forward. THE KID LOVED THE PRESENTS! Honestly I believe he liked it more than all those cards he got with the 20 dollar bills stuck inside them. He saw the toilet paper roll as... DUN DUN DUN. A TELESCOPE! He said "Cool! I can use this to play pirate!" (which was what my sister said!).
Oh kids. Conclusion? I don't have the imagination you guys have anymore. Right now I blame my parents for the generation gap that we have, but honestly generation gaps are really hard to close! I am only 8 years older than my sister, and yet I can't even think the way they do anymore. I can't see a piece of paper as a treasure, nor do I see a telescope from a paper roll.

ADULTS, WE SUCK :(

possible solution? SPEND MORE TIME WITH YOUR KIDS!
(hah jaykay I don't know Im only a sister I don't have kids :( so dont listen to me_)
