he wants you to move on. he wants you to realize its been over since 2 summers ago. he wants to be friendly without you misinterpreting it to mean he wants a relationship. he wants you to stop the R talk. he wants you to know he doesnt want a R with you. he wants to work together and give you coffee, which is just coffee and not an offer of reconciliation in a Tim Hortons cup. he wants you to stop thinking "he's not ready" or "confused" or going to change his mind.
