Connecting with students by sending notes and cards. You can send them for birthdays, to say hello, to let them know you’re praying for them, inform them of upcoming events. No matter what the occasion, notes are a good way to communicate and stay connected. You can find cheap ones at the bookstore (8 little notecards for $.99), so they won’t break your budget either.
Only putting a 26 cent postcard stamp on them. They will not get delivered.
lesson: pay more attention to which stamps you pick up when sending mail out. Or just be willing to face the “embarrassment” of having a stamp and the “post office” stamp on the same envelope showing you messed up.
