I went to a concert of Spanish music from the XV and XVI centuries last Friday at the Universidad Central de Venezuela. After a magnificent performance I was sipping a nice cup of coffee when I saw this female dog running around the building of the Engineering School. I realized that she entered the building so I followed her. She wasn't anywhere in sight, then I saw her inside the Library/Study Hall.
She is very smart, the place has great air conditioning!
Not everybody understand her need for getting in and getting out every 2 minutes, so she stands there until a good soul opens the door for her. It is a delight to watch.
