Finding my way - part 2

[Meghan]

Question: H.'s birthday is coming up. I've sent a funny card but neutral card that I signed, but don't know what I should do on the actual day.

Should I wish him a happy birthday...

Through a phone call? (After barely talking for a week and a half, I'm concerned this could feel awkward)

By email? (This is more impersonal, but wouldn't interrupt him if he was doing something else)

Over IM? (This is a pretty typical way of communicating and chatting for us - it wouldn't interrupt him if he was doing something but would still probably have us chat a little bit)


In any case, what do I say or not say to him? I definitely plan to stay away from mentioning the relationship, missing him, or his upcoming return home unless he brings them up. I also probably won't mention much about my trip and what I did. Is there anything else it would be good to say or good to avoid, though?
