recycling LORs?

[lexylit]

i know it sounds tacky, but is anyone using an LOR that's already on file?

i've already got two shiny new ones going, but they're form grad school and work. i obviously need to call up my ug thesis advisor and tell her i'm not going to be an english prof, but a lawyer. i'm scared. so i'm kinda thinking why couldn't i send on the one i've already got on file from grad school apps? 

also, is anyone leaving out ug recs altogether... i'm guessing no?

Yup. I'm almost 10 years out and can't expect any of my professors to remember me, really. I was a rather undistinguished undergrad. Even better -- I'm not even getting recs from any of my MS professors. Half the classes were online and I never had the same prof twice.
