she likes carrying around random rags for no reason
This is actually a common trait of golden retrievers! They’ll do it with toys, socks, rags, etc. Holding things in their mouths acts kind of like a pacifier to them and is much like a coping mechanism to help them handle their emotions (both good and bad). Our golden usually grabs our socks and carries them around when happy to see us, or when she gets scared or embarrassed.
what if i died in like twenty years and all i left my girlfriend was a box and like she gasps and reaches down to her chest where her key necklace hangs that i gave her twenty two years ago, and she uses it to unlock the box and all that is in there is a string which you can pull to reveal an embarrassing photo of spongebob at the christmas party
