So today, my ¹⁸ year old sister made the decision
to break up with her boyfriend of ^{three years.}
She's really upset about it,
and when she went to tell my dad,
he got mad and basically said she's not allowed to do that.
Click the ♥ if you think this is wrong and that she needs to make her own decision.
