why can't i 和why i can't分別

why can't i write chinese here!!! 啱
why i can't write chinese here!!! 都啱

我覺得係咁ge分別
例如:
1. Why Can't Women Ski Jump
個意思係男女平等, 女人都識ga, 點解女人就唔可以ski jump?

2. Why Women Can't Ski Jump
個意思係點解女人就係唔識ski jump, 呢度就講到個人能力啦

又好似:
1. why can't I imagine
個意思係點解我就冇權想像wor?
2.why I can't imagine
個意思就係點解我連想像ge能力都冇
