Back my English studying

I thought have been thinking hard today about some things : about my work and English studying ... and that ONLY I myself can help myself me. I thought about think of my limitations/shortcomings limited things and strong points too. I may be too lazy last and waste time eating, sleeping and chatting (you have to eat and sleep, it is no waste of time :D) ....I am lucky to meet some nice friends in this virtual world but there are bad guys too.
I woke was woken up by my mom's phone call calling this morning. She asked me 'to will you come back home today?' That was great i cant do (??? I don't understand) . I started my Sunday with a glass (usually we say 'cup' but I know the Vietnamese style is a little glass) of black coffee with added a little sugar added , i prefer milk coffee but i limit it now because i am scared i will be get fat hehhehe (you can buy low-fat milk). I cooked lunch then and went to my friend's pharmacy nearby near here. I did have not visited her for a long time by because of my work and my being lazy ,lol...Well, her pharmacy is larger than now, there are many new medicines that i don't know much about forgot a bit of them,so I thought i need to look at them up again. I bought some meds for my father and mom. They are not so well fine now (mum told me on the phone). I am was sad to hear that but and i can't take care of them at the moment. My friend talked me so much about her work, her daughter and both her drugs businesses biz. Everything sounds good and process is progressing well. I am happy for her.
I refusred ('declined' is a softer word here) her dinner invitation because i am was afraid of it is would rain and be too dark. I came by , i drive my motobike, it will not nice and safe on the street at night then. I think i had a nice time together with her and I am so interested when i sometimes go out,  to discover more of life around me....
Time for bed, wish hope i have a good week and work well on tomorrow .
