字源記憶法自撰
框 · Frame
[subj] 對 [target person] [verb phrase]
觸 · Trigger
You want to say an action is directed at a person you face — speak to them, smile at them, behave toward them.
序 · The move
1Put the doer first, then 對, then the person faced.Is the slot after 對 the receiver, not a second doer?
2Place the verb phrase after the person.Does the verb land on the faced person, not travel as motion?
3Read it back from the picture.Does 對 mark who is faced (success), not who does the facing (failure)?
例 · Examples

界 · Boundary
對 aims an action at the person you face (對我笑 = smile at me); 向 orients or heads toward a direction or target (向我走來 = walk toward me). 對 faces a recipient; 向 points a path.
對 marks a one-way recipient — you face them and act on them. 跟 marks a co-actor — both do the one thing together (跟我說 can be mutual conversation; 對我說 is speech aimed one way at me).
✗ 我笑對他 → ✓ 我對他笑 (對 + person comes before the verb, not after)
✗ 對他跟我說話 → ✓ 跟他說話 (mutual talking takes 跟, the co-actor marker)
✗ 對著公司走 → ✓ 向公司走 / 往公司走 (heading toward a place is 向/往, not 對)
English 'at/to' collapses several markers; the smile in 'smile at me' is 對, but the walk in 'walk to me' is 向/往. 對 needs a person being faced, not a destination.
