It’s funny when wanting to express you are grateful (བཀའ་དྲིན་) to someone you place the ལ་དོན། to yourself!
ང་ལ་ལུག་ནག་པོ་ལགས་ལ་བཀའ་དྲིན་ཆེན་པོ་ཞེ་དྲགས་ཡིན།
Franziska-la gives us the mnemonic of thinking of being kind to as opposed to being grateful, and the ཡིན། would still work because despite speaking of someone else (non-egophoric) it still has a strong effect or relation to you.
