Wanneer u met iemand wilt daten, vul dan eerst even uw leeftijd hier in. Zo ziet u gelijk of uw leeftijdsverschil sociaal acceptabel is.
The idea is that it would be creepy for a person to have a romantic relationship with someone that is too young for them, but what, exactly, is this age? A western rule-of-thumb is to take your age, divide it by two, and add seven to that (you + 7). them = you + 7, then we simply swap "them" and "you", then solve for "them". This gives us them = 2 × (you - 7)
