For Havest Moon DS I can't get into the house of the villagers?

Question

My Game when I go into a house of the villagers it won't open even if I go at the right time can someone please help me what to do

Answer 1

you can't get into the house because no one is home.

if someone is home, and you can't open a door (for example, the door inside the scientist's house) sometimes you need to raise your friendship level with that person

Answer 2

you could have ghost town glitch or holiday either way check tommorow
