The simple thing i can't do

When see you bring your shopping stuff
I say,
"In the last time, i could bring it too, same with you"

When see you eat he delicious food
I say,
"In the last time, i could eat it too, same with you"

When see you wear the quality stuff
I  say,
"In the last time, i could wear it too, same with you"

When see you smile and laugh honestly
I say,
"In the last time or now, i can't do that"
