Well, If the nerdy guy has potential of being cute at all then they blush maybe because either one he's funny and or two they like him. Girls nowadays like nerdy guys. mainly because there sweet, funny, someone they can be just as nerdy with, and know they wont take advantaged of there love.
he likes you
It means they just want the answers for the hw...duh but if ya play it right the nerdy guy can get somethin out of it too;)
that means that she likes him or is attracted to him in some way bcuz girls almost 98.9% of the time usually blush around a guy when she is interested in him. I should know cuz im a girl and i always blush ALOT when im around a guy that i like ;)
sound amazing...
it could mean a number of things. the girls could be expressing silently that they like him/find him attractive or they could be feeling sorry for him if he has something outwardly wrong with him (like his fly bein unzipped or having something in his hair).
Nerdy guys are more attractive then they realize, in my opinion anyway ;] If these professors are considerably older though...that's a tad strange. Remember that inside every woman is a teenage girl =]
Girls tend to blush around guys they like.
It means u have a gift
It means that nerd must be good looking or shes the one for him:)
They have feelings for you
Usually, girls are mean because they get jealous. If they try to bring someone down, it just means that person is higher than them.
well i think that if this happens than you juss honestly have a crush:) and that's not bad att allll!! nerds can be cute and theyre not always as jerkey as other guys.
