他大概太高注意不到我
[tā dà gài tài gāo zhù yì bù dào wŏ]
Translated as 'He might be too tall to notice me,' this indicates feeling overshadowed or overlooked by someone considered superior (not only in height but in status, ability, or popularity), reflecting a bit of self-deprecation or melancholy in unreciprocated love/attention.
