I'm A Young Man - She's A Woman?

Ok - you might call this hormonal - I'm a young man under 21 and there's this girl I can't get put of my head - she's beautiful and it's tragic, she lost her husband a couple of years ago - her son comes for instrumental lessons and he's a real character, i enjoy his enthusiasm - the thing is - his mom is years older than me - but she's beautiful, brave - i think she's everything I would like for in a partner. I surely can't imagine she could feel the same way for me - but her son looks up to me I suppose, there's nothing greater than this feeling that I'm enriching his life somehow - I'm young, but I don't aspire to be foolish like many people my age - if this can make sense - life with these people could be amazing - am I wrong to believe I could be a part of it?
