If you want to order stuff, you just have to watch tv on saturday. After that, you go to
Inn then go to the phone at the counter. Click it then make a call.

If you are holding an edible item (food, etc.), Left Shoulder+ B will make you eat it. You
can also rotate through your tools by holding down the Left and then using Right or Left
on the directional pad.

How to get married:
After the bachelor's heart already change color to red, you can propose them! You will buy
a blue feather at Jeff's market then use it to propose the bachelor!

Hope I'm helping you! ^__^
