cshapiro i always thought u were a guy.
it depends on ur age whether u shud stand up for a female thats the same age
if you are 17 you shouldnt because at that age they have no problem standing so clearly your motive is to talk to her
if you are 45there is still no need because she can stand fine and she is probably married so you shudnt talk to her
if you are in your 60s than u shud ask her if she wantsa to sit but if she says no dont insist
if ur in ur 80s definately stand up because if u dont she will probably tell you straight to ur face that ur disrespectful for not getting up
