[@strawverrymilktae410]

Not just you

[@smilezsmiley8223]

You guys forget that even though you didn't understand the constant reminder and having a little knowledge helps in understanding also you don't just listen in class then go home and expect to remember again the next day

[@freddiesdiaryy]
