The teacher is pleased; her hand is perfectly wet; she can move on to the second, practical and important part of her lesson. ๅ ็ใฏๅฐ้็ฅ่ญใ้งไฝฟใใพใใ ใขใซใขใใใฎๅค้ฐ้จใๅฎๅ จใซ่ๅฅฎใใใใ้ฐๅใฎไธ้จใซๅงๅใใใใใ ใใงใๆฝคๆปๆงใฎ้ซใใณใผใใฃใณใฐใใใฃใใใจๆฝใใใพใใ ่ฆชๆใงๅตๅทฃไป่ฟใๆผใใใๆฎใใฎๆใงๅคง้ฐๅใซ่กๆถฒใ้ใ่พผใฟใ่ ซใใ่จใใฟใ็ใใใใพใใ ๅ ็ใฏๆบ่ถณใใงใใๆใฏใใฃใใๆฟกใใใฎใงใใฌใในใณใฎ2็ช็ฎใฎใๅฎ่ทต็ใง้่ฆใช้จๅใซ้ฒใใใจใใงใใพใใ
