A fear of anyone older and/or younger than you. This could also apply to people the same age as you. Some cases of agephobia are very mild, such as only feeling uncomfortable around people older/younger than you. More severe cases have more discomfort, fear, and unwillingness to do anything with people outside of your age group.
Person 1: Hey! There's a party this weekend at my house. You wanna come?
Person 2: who's going to be there?
Person 1:just you, me, a few other friends, and my older sister and some of her friends.
Person 2: I'd rather not, your sister gives me agephobia.

Person 1: ok. It's fine.
