Or somebody who recognizes you from way back when
So weird, but always a pleasant feeling.
Are you talking about an internet friend or someone from RL that you meet after a long time on the internet?
If it is the former, then it's definitely a great feeling especially since people often just disappear from the internet.
@Ranger Jack Walker; Yup, internet. Although in my case it was probably me who seemed to disappear. Either way contact was severed...but now it's not.
