Well normally I would just ask them how they were, then go from there, I don't normally use anything more than *huggles* or *Paws at* etc. unless it's on a forum I do not Roleplay.
If it is in real life, I'll greet them either by a handshake, a smile or a hug, depending on their preference, ask if they're having a good day and about certain aspects about it, crack open the humour bucket and then have a smashing old time
