Growing Up

So here I am in ND by myself (well, I am visiting my mom, but without Chan and the kids) and I went over to visit my grandparents tonight. All of a sudden it struck me that they are really old. I don't mean this in a disrespectful way, but for a moment, I was frozen and could only stare and think to myself  "when did my grandparents get this old?". It was shocking to have that realization. All of these amazing memories were rushing through my head: summers at the lake with my Grandma, riding bikes to the store with my Grandpa, the treats they used to buy us...

It really made me sad! Does everyone have this happen? My mom really doesn't seem any different to me...I am still wondering how I got this old! It's a crazy thing this growing up!
