Do lemon and lime have other citrus friends?

Seems like they are always together. You’d think every once in a while they’d invite their pal the grapefruit over. We’re sure they will when the citrus family gets together. Like on Lemon’s birthday or something. Maybe at that citrus party they’ll serve Lemon Lime Carbliss.

Which will remind all the other citrus that lemon and lime are inseparable. And awesome.
