not my day

just not my day today. first contact lens made my eyes so dry that i don't think i can wear lenses for a week.
not only did it leave me with 'desert' eyes, the right side was so blurred. i can't read or make out people's faces if they are a distance from me. this never happened before.
work was ok. didn't have much 'eca' as my programme manager calls it. did the usual stuff n surfed the net a bit.
then the other incident that really spoiled my mood/appetite/everything was thanks to sis dearest. accompanied her to get a laptop casing. found what she was looking for at Funan. then we were supposed to go for dinner at Sarpino's Pizza @ Simei.
she wanted to get some buah asam for her throat. found a shop selling preserved fruits and finally she chose something. before paying, i asked the shopkeeper if that preserved plum was of a sour variety. she replied it's sweet & sour. sis dearest said it was ok so i bought it.
turned out it was more sweet that sour and guess who gets the blame. how would i know what the thing will taste like. there was no tester in the first place. even if there is a tester i wouldn't be able to taste it. i was fasting!! she knows it.
i offered to make it up to her by getting something she wants. went into Cheers and she got herself a box of Strepsils. after paying for them, she declared she's out of money and wants to go home.
well suit yourself. i walked over to Bugis without looking back. was really disappointed that i really lost my appetite. all i had for buka was the preserved plum she almost threw at me. told mother i've already eaten.
at Masjid Sultan, a lady asked me to help her pin her tudung. asked if i'm Singaporean. i gladly helped her and answered her i'm 100% Singaporean. made me think, how nicely a stranger we treat but how crude a family is treated.
is there any way that i can resign as a post of sister? what's the point of being a sister, an elder one too, when your advices are not heard? it's labeled as nagging instead. is there any way i can step down and not have any responsibilities of a sister? what is the point really?
i'm the one PMS-ing now. i'm the one who has the right to get upset and get mood swings now. how come it's me who is getting the brunt of it? what am i?
what is the point, really? :(
