brothery love

One morning at previous shop, I heard weird nose from my empty trash can.
found 4 mice at bottom of it. This trash is about 40 inches deep,some of them trying jump out.But not high enough and slippery plastic won't help either.. then i am thinking how did they get down there? all 4 of them?..
probably one of them fell, then screamed for help,, others came down to rescue but got stuck..
family? brothers? sisters? I don't know,, but this tiny creatures with brain size of sesame seed have know how to love each other.

I flipped the trash can to let them go..

this happened again ,,they don't know how to learn a lesson I guess..
