I almost quarrelled with mom about aseng just cos he walked past by us while we were eating, i didnt call him made my mom upset saying im ill-mannered brat...I just blunty told her he mistaken ppl's feelings so easily. Just smilng at him he thought i liked him..OMYGOSH..how can u smile u straight away say that ppl like u? what the hell..so got no choice i just lied to my mom i already have a boyfriend! my mom insisted that i shld bring him to house to let her see him...this is soooo getting over the limit..all just bcos of that stupid total stranger who mistakenly thought ppl smiling being kind to him means liking him...What to do what to do?~!!!
