@dorispulaski just curious about the lilsis name - did you say it's a nickname? I used to work with someone who often referred to her younger sister as "lilsis." Also her dad would call her (she was the middle child) "sis" or "sister" instead of her given name quite a bit. Wondering if it's a cultural thing or just a coincidence.
My friend Deb's (the only I worked with) family is Polish so I wondered if maybe it was a Polish or Eastern European tradition of some sort. Always thought it was cute that her dad called her "Sister."
