I've been accepted to a MA in the fall. Working on PhD applications now. Spoke with my UG thesis adviser, thanking him for LoR for the MA. He wrote in an email that getting a LoR from someone in my future MA program would be more meaningful for me.
"Recommendations have a half-life of about one year...Mine won't mean much."
I went to a top school and he advised my thesis. If I don't have him, isn't that a huge red flag? I haven't formally asked him for a PhD LoR. Is this a polite pre-emptive no?
An anecdote or advice would be much appreciated. I'm freaking out quite a bit.
