Yes, you are right. I don't think these sentence are strange. But we usually too shy to say LIKE to other person. Even to family and friends, we (I) don't say " I like you" as often. That's why someone misunderstand and say ' What? you love me?' It easy to say ねこ/ いぬ/すし/ さしみがすき, however, I wonder why it difficult to say かれ/ かのじょ/あなたがすき!Woooo just thought of this, I am so embarrassed!!
