Help me with slumber party invite wording- tricky situation

[Anonymous]

I like the approach of being clear about what is expected: boys dropped off at 10 or 11, girls the next morning.

For the parents that think it is ok for 11/12/13 yo's to sleep over (opposite sex) because there has been no interested expressed. The key word could be expressed. Between the 6th and 7th grade, I (male) spent the summer at my grandmothers. The only kid that was about my age was her neighbor's (next apartment) granddaughter. We basically hung out all summer together. We developed feelings. And we fooled around (mostly clothes on). We did see and touch each other.

No one knew what was going on. In public, we were just friends.
