<human>: Hi everyone, 
I've known a few people who entered into relationships with previous teachers/professors after they were no longer in their classes. I'm just wondering if anyone can give me some heads up for the negative things that could come from it, because I don't feel comfortable asking the people that I know.

To keep this short, I have a high school teacher that I recently re-connected with. We'll call him Jeff. Jeff was always one of my favorite teachers in high school, because he is a very kind and funny person. I've just always liked him and came to him for advice a couple of times. We recently met after not seeing each other for 2 years and he gave me his phone number and invited me to dinner. He didn't specifically call it a date, but I'm sure that was the implication because he was also mentioning things about how I look/complimenting me and asked if I was seeing anyone (I'm not).

So...how bad would this be? It feels really wrong for some reason but it also feels like it's not that bad, I mean he hasn't been my teacher in years and I don't attend the school he works for anymore. I'm a little worried that this could cause some personal turmoil or something. I don't know if it's relevant but I've had crush on several teachers (nothing serious at all, never has been anything more than fantasy) so I'm a little worried about actually having the opportunity to act on it. I would appreciate your guys' advice, thanks!

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Wondering what your guys' thoughts are on dating a teacher from high school, I don't go to the school anymore and haven't had him as a teacher in several years.
