What the hell is up with this teacher and food!

My teacher brought in cake/sweets for our class because it was end of term. He does this usually, it is really lovely of him he has brought in things like Krispy Kremes for our year 12 (like 11th grade?) sixth form class before, and only us not the other classes he teaches, which is really nice.

The other day it was our last lesson with him of the term and he had brought in swiss roll and other sweets. It was like 9 in the morning so I didnt feel like cake.

He came around with the food and I said no thanks and he was like ‘okay’. Everyone else was quite happily taking as much as they liked.

Then he came right to me (i.e. he wasnt just casually offering it around, he made a beeline for me), and asked a second time if I wanted any and I said ‘no thanks’ and he replied ‘well.. why did i bother bringing all this in then…’, and trailed off, but it wasn’t as rude as i am making it sound on here. I didnt quite understand that because there were 6 other people in the class happy to eat it, (it is a really small class) even though i didnt want any.

Then he asked me a THIRD time if I wanted some cake/sweets and I said no thanks he asked me ‘why?’ like he was genuinely interested, and i replied ‘I just dont feel like any’ and he said ‘Okay’ this time mocking my english accent in a jokey way (he does this anyway, because he is from the north of britain so has a different accent)

THEN FOR A FOURTH TIME (it was getting irritating now) he asked me if i wanted any and i said no.
Again.

FINALLY at the end of the class the bell was about to ring he said ‘here just take this last piece of cake’ and I gave in and said fine and he brought it over to me in a tissue and i took it from his hands and he said ‘there, go wild’ all sarcastically.

He wasn’t mad at me as we chatted and smiled like usual in the hallway later etc, and when I was leaving the class right after he gave me the cake he was in the middle of talking to someone about their work then i heard him cut himself off mid sentence to them, to say “Bye ____, have a good easter!” to me as i was slipping out of the door quietly.

The food thing was weirding me out, i said no once, twice, FOUR BLOODY TIMES, and he still kept asking me if i wanted some. I usually eat whatever food people bring in, it was just that morning. no im not anorexic, i dont look anorexic i am healthy, so it cant be that he was worried about my eating habits.

there was another girl in the class not really eating anything either and refusing food but he didnt bother her about it, just me. which is why it is pissing me off.
anyone have any idea what the hell was going on?? he is one of the nicest/coolest teachers we have. very down to earth, chats like a normal person (i.e. he swears sometimes, tells stories involving his own life, but nothing inappropriate)
but this thing that happened is really annoying/confusing me.
