Advice.

Hi everyone. I’ve known this guy since we were around 2/3 years old. We’ve not spoken a lot in the past few years haven’t bumped into him( he-lives next door to a relative I visit regularly) we’re both 23. Anyway a few days ago he was out in the back yard and so was I (I was visiting the relative) and we started chatting (he initiated the chat) we were speaking about 10/15 minutes. I showed him some photos my relative found out from when we were around 4 year old. I’ve tried to contact him and had no joy (messages not sending) anyway I managed to find his mums number so I’ve text her. She told me he mentioned we were chatting and that I showed him the pictures. She told me to keep in touch and told me to look after myself. Does the fact he told his mum mean anything at all or just that he’s glad we had the time to talk. I’ve told her to let him know my number to pass it on and that I’d like to see him sometime soon for a drink to catch up. Thanks everyone
