First of all, I received many a humorous voicemail in this process. She and her daughter came by to look at the sofas and decided they wanted them but have no truck and, what became apparent to me, no males to assist them. It looks like I'll likely have to be calling a friend with a truck and we'll have to do the moving for them.
Definitely not something I would have considered doing for someone buying these before but damn it, when you have a nice little old lady in your apartment with no way to move any furniture for her new place it becomes exceedingly difficult to not offer to help. So word to the wise, never let little old ladies into your home or you will find yourselves compelled to labor for them.
