I suppose that counts - if you extend the definition of sisters to include ponies that aren't actually related by blood, but are as close as sisters.

@AthleticDashie: Pretty sure GG is talking about siblings, as in "those in your immediate family, not counting your parents" - parents don't factor into the question of whether you're an only child or not.
