My nephew Thomas just turned four. Technically, his birthday isn't until Tuesday, but for logistical reasons, we had his main birthday celebration today. Thomas is going to have another one on Monday with his nanny and then another one on Tuesday, too, so it might be more accurate to say that is celebrating his birthdays in the plural.
Last year, he really wasn't all that interested in gifts, he disliked sweets, and he would rather avoid most people, so there wasn't much interest in a b-day party.
This year, he had been looking forward with some impatience to the birthday cake he would receive, he actually enjoyed the celebration, and his greed had increased dramatically.
