<human>: So. I know how bad/strange that sounds, but seeing as my own parents are 10 years apart, it doesn't register as weird to me. Anyway, I've been at this place for 8 months and I really like this one coworker of mine. He's gentlemanly, kind and VERY intelligent, but rather shy. I truly do not know if he likes me. I'm very bad at telling if he does. What I do know is that he smiles and says hi when he sees me, i catch him staring at me alot (sometimes he doesn't smile then though :( and I've caught him checking me out once) And, whenever I ask him to get lunch with me, he always goes. (however, he himself hasn't asked me yet.) I've been super professional and tried really hard not to stare at him and just focus on my work. I think he thinks I don't like him now...but I've found a new job and will be leaving in a few weeks. 

Should I ask him out on my last day? I'm not even sure if he'll be ok with it, given our age difference. Would guys be offended if a girl does that? 

Part of me is worried he'll parade it around the office if I do so. Also, just really not sure if this is ok. For those of you who've met your s/o at work, how did that happen?  
Oh, and clicked his schedule and saw that he'd marked "stepstools_are_mybff's last day"....he did that not me, and I didn't tell him when my last day would be

I might: 
A. Write my number on a post it note and just be like "here's my number if you want to stay in touch" 
B. Write out a cute little card about how I think he's smart/awesome and add my number...basically showing all the cards
?????????

Can you give me a shortened version of the text?
<bot>: crushing on soon to be former co-worker, afraid to ask him out. Should I just let this one go?
